In the bizarre realm of quantum physics, a quiet revolution is taking place, where the impossible becomes possible. Electrons spin both right and left simultaneously, and particles change states in unison despite vast distances separating them.

These intriguing phenomena are commonplace in the quantum world, and researchers are harnessing their power to revolutionize computing, sensing, and communication.

At the Walther Meissner Institute (WMI) on the TUM Garching research campus, Professor Rudolf Gross and his team are pushing the boundaries of quantum technology.

We cool the chip down to only a few thousandths of a degree above absolute zero colder than in outer space, explains Gross, gesturing towards a delicate device with gold-colored disks connected by cables.

For two decades, WMI researchers have been working on quantum computers, a technology that emerged from the quantum physics revolution a century ago. Today, this field serves as the foundation for what Gross calls a new era of technology.

We encounter quantum physics every day, says Gross, citing the example of a glowing red stovetop burner.

Max Plancks discovery of quanta in 1900 fundamentally changed our understanding of the microcosmos, paving the way for technologies like lasers, MRI machines, and computer chips.

While the first quantum revolution controlled large numbers of particles, the second quantum revolution focuses on manipulating individual atoms and photons.

Today we can create tailor-made quantum systems, says Gross, leveraging principles like superposition, quantum interference, and entanglement.

Classical computers process information sequentially, limiting their ability to solve complex problems efficiently.

Quantum computers, however, use quantum bits (qubits) that can process 0 and 1 simultaneously, enabling parallel processing and quick solutions to highly complex tasks.

Not even supercomputers which are constantly growing faster will be able to master all the tasks at hand, says Gross, highlighting the potential of quantum computing to tackle problems that become overwhelmingly complex for classical computers.

Quantum computers need hundreds of qubits to solve practical problems, but qubits are prone to losing their superposition due to disturbances like material defects or electrosmog.

Complex error correction procedures require thousands of additional qubits, a challenge that experts expect will take years to overcome.

Dr. Kirill Fedorov of the WMI proposes distributing qubits across several chips and entangling them to reduce errors.

One important error source is unwanted mutual interaction between qubits, he explains, suggesting that this approach could enable thousands of qubits to work together in the future.

The fact that quantum states react so sensitively to everything can also be an advantage, says Professor Eva Weig, a pioneer in the field of nano and quantum sensor technology.

She believes that this inherent sensitivity of quantum systems can be harnessed to create a new generation of highly precise and responsive sensors by leveraging the way quantum states are altered.

Weig envisions the development of quantum sensors capable of detecting minute changes in magnetic fields, pressure, temperature, and other physical parameters with unprecedented accuracy and spatial resolution.

Weigs team is working on nano-guitars, tiny strings 1,000 times thinner than a human hair that vibrate at radio frequency.

By putting these nano-oscillators into a defined quantum state, they could be used as quantum sensors to measure forces between individual cells.

Professor Andreas Reiserer is exploring quantum cryptography, which relies on the principle that measuring a particles quantum state destroys the information it contains. Quantum cryptography is cost-effective and can already support interception-proof communication today, he says.

However, the scope of this technology is limited by the absorption of light in fiber optic cables. Reiserers team is researching quantum repeaters, storage units for quantum information spaced along fiber optic networks, to enable long-distance quantum communication.

This way we hope to be able to traverse global-scale distances, Reiserer says, envisioning a future where devices worldwide could be linked to form a quantum supercomputer.

As quantum technologies become more prevalent, its crucial to consider their ethical, legal, and societal implications. Professor Urs Gasser, head of the Quantum Social Lab at TUM, warns that the cost of arriving too late to the quantum revolution could outstrip the cost of being late on artificial intelligence.

The good news is that there are already new encryption procedures which are secure against quantum computer attacks, says Gasser, stressing the need to start preparing for the transition now.

Gasser emphasizes the far-reaching impact of the quantum revolution, stating, The second quantum revolution is a paradigm shift which will have a far-reaching social, political and economic impact. We have to shape this revolution in the best interests of society.

In summary, as researchers at the Garching research campus lead the charge in harnessing the bizarre phenomena of quantum physics, the potential applications of quantum technology are vast and far-reaching.

From quantum computers that can solve complex problems in a fraction of the time to quantum sensors that offer unparalleled precision and sensitivity, the future is undeniably quantum.

However, as we embrace this new era of innovation, we must also consider the ethical, legal, and societal implications of these advancements.

By actively shaping the quantum revolution with the best interests of society in mind, we can ensure that the benefits of these technologies are widely accessible and that their impact is overwhelmingly positive.

Successful demonstration of a superconducting circuit for qubit control within large-scale quantum computer systems

TOKYO, June 3, 2024 - (JCN Newswire) - In support of the development of large-scale superconducting quantum computers, researchers with the National Institute of Advanced Industrial Science and Technology (AIST), one of the largest public research organizations in Japan, in collaboration with Yokohama National University, Tohoku University, and NEC Corporation, proposed and successfully demonstrated a superconducting circuit that can control many qubits at low temperature.

To realize a practical quantum computer, it is necessary to control the state of a huge number of qubits (as many as one million) operating at low temperature. In conventional quantum computers, microwave signals for controlling qubits are generated at room temperature and are individually transmitted to qubits at low temperature via different cables. This results in numerous cables between room and low temperature and limits the number of controllable qubits to approximately 1,000.In this study, a superconducting circuit that can control multiple qubits via a single cable using microwave multiplexing was successfully demonstrated in proof-of-concept experiments at 4.2 K in liquid helium. This circuit has the potential of increasing the density of microwave signals per cable by approximately 1,000 times, thereby increasing the number of controllable qubits significantly and contributing to the development of large-scale quantum computers.The above results will be published in "npj Quantum Information" on June 3 at 10 a.m. London time.

According to a recent release, NXP Semiconductors has partnered with eleQtron and ParityQC, with theQSea consortiumof theDLR Quantum Computing Initiative (DLR QCI), to create what is reportedly the first full-stack, ion-trap based quantum computer demonstrator made entirely in Germany. The new quantum computer demonstrator is in Hamburg.

Hamburg is one of our most important R&D locations. We are proud that, together with DLR and our partners eleQtron and ParityQC, we are able to present the first ion-trap based quantum computer demonstrator developed entirely in Germany, said Lars Reger, CTO at NXP Semiconductors. We are convinced that industry and research communities in Hamburg and throughout Germany will benefit from this project. It will help to build up and expand important expertise in quantum computing, to use it for the economic benefit of us all, and also to further strengthen our digital sovereignty in Germany and the EU.

The goal of this demonstrator is to enable early access to quantum computing resources and help companies and research teams leverage it for applications like climate modeling, global logistics and materials sciences, the companies said.

DLR QCI says it aims to build necessary skills by creating a quantum computing ecosystem in which economy, industry and science cooperate closely to fully leverage the potential of this technology. Quantum computers are expected to tackle complex problems across industries, and will likely dramatically change the cybersecurity landscape.

NXP, eleQtron and ParityQC have used their expertise to build this ion-trap based quantum computer demonstrator by combining eleQtrons MAGIC hardware, ParityQC architecture, and NXP chip design and technology. To speed innovation and iteration, they have also developed a digital twin, which reportedly will be used to help this QSea I demonstrator to evolve to a quantum computer with a modular architecture, scalable design, and error correction capabilities. That evolution will be the goal of the ongoing work with the project.

The demonstrator is set up at the DLR QCI Innovation Center in Hamburg and will be made available to industry partners and DLR research teams, the release said. The three partners and the DLR QCI say they aim to foster and strengthen the development of an advanced quantum computing ecosystem in Germany.

To achieve a leading international position in quantum computing, we need a strong quantum computing ecosystem. Only together will research, industry and start-ups overcome the major technological challenges and successfully bring quantum computers into application. The QSea I demonstrator is an important step for the DLR Quantum Computing Initiative and for Hamburg. It enables partners from industry and research to run quantum algorithms on real ion trap qubits in a real production environment for the first time. This hands-on experience will enable them to leverage the advantages of quantum computers and become part of a strong and sovereign quantum computing ecosystem in Germany and Europe, said Dr.-Ing. Robert Axmann, Head of DLR Quantum Computing Initiative (DLR QCI).

Entanglement is a key part ofquantum computing

Bartlomiej K. Wroblewski/Alamy

While scientists generally try to find sensible explanations for weird phenomena, quantum entanglement has them tied in knots.

This link between subatomic particles, in which they appear to instantly influence one another no matter how far apart, defies our understanding of space and time. It famously confounded Albert Einstein, who dubbed it spooky action at a distance. And it continues to be a source of mystery today. These quantum correlations seem to appear somehow from outside space-time, in the sense that there is no story in space and time that explains them, says Nicolas Gisin at the University of Geneva, Switzerland.

But the truth is that, as physicists have come to accept the mysterious nature of entanglement and are using it to develop new technologies, they are doubtful that it has anything left to tell us about how the universe works.

You can create quantum entanglement between particles by bringing them close together so that they interact and their properties become intertwined. Alternatively, entangled particles can be created together in a process such as photon emission or the spontaneous breakup of a single particle such as a Higgs boson.

The spooky thing is that, in the right conditions, if you then send these particles to opposite sides of the universe, performing a measurement on one will instantaneously affect the outcome of a measurement on the other, despite the fact that there can be no information exchanged between them.

For Einstein,
