New research shows that metasurfaces could be used as strong linear quantum optical networks This approach could eliminate the need for waveguides and other conventional optical components Graph theory is helpful for designing the functionalities of quantum optical networks into a single metasurface In the race toward practical quantum computersContinue Reading
On July 8, 2025, physicists from Aalto University in Finland published a transmon qubit coherence dramatically surpassing previous scientifically published records. The millisecond coherence measurement marks a quantum leap in computational technology, with the previous maximum echo coherence measurements approaching 0.6 milliseconds. Longer qubit coherence allows for an extended windowContinue Reading
Twisted materials — known as moiré structures — have revolutionized modern physics, emerging as today’s “alchemy” by creating entirely new phases of matter through simple geometric manipulation. The term “moiré” may sound familiar — it describes the strange rippling patterns you sometimes see when photographing striped shirts or screens; inContinue Reading
Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum world. This second law of entanglement manipulation proves that, just like heat or energy in an idealized thermodynamics regime, entanglementContinue Reading
Quantum computers still face a major hurdle on their pathway to practical use cases: their limited ability to correct the arising computational errors. To develop truly reliable quantum computers, researchers must be able to simulate quantum computations using conventional computers to verify their correctness – a vital yet extraordinarily difficultContinue Reading
Quantum computers have the potential to speed up computation, help design new medicines, break codes, and discover exotic new materials — but that’s only when they are truly functional. One key thing that gets in the way: noise or the errors that are produced during computations on a quantum machineContinue Reading
Scientists from TU Delft (The Netherlands) have observed quantum spin currents in graphene for the first time without using magnetic fields. These currents are vital for spintronics, a faster and more energy-efficient alternative to electronics. This breakthrough, published in Nature Communications, marks an important step towards technologies like quantum computingContinue Reading
Quantum computers can solve extraordinarily complex problems, unlocking new possibilities in fields such as drug development, encryption, AI, and logistics. Now, researchers at Chalmers University of Technology in Sweden have developed a highly efficient amplifier that activates only when reading information from qubits. Thanks to its smart design, it consumesContinue Reading
Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also key in security; if a password or code is an unguessable string of numbers, it’s harder to crack. Many ofContinue Reading
For decades, quantum computers that perform calculations millions of times faster than conventional computers have remained a tantalizing yet distant goal. However, a new breakthrough in quantum physics may have just sped up the timeline. In an article published in PRX Quantum, researchers from the Graduate School of Engineering Science andContinue Reading
