Scientists have demonstrated that wires more than 100 times thinner than a human hair can act like a quantum one-way street for electrons when made of a peculiar material known as a topological insulator. The […]
Measuring entanglement without destroying it on commercial quantum computers
In quantum mechanics, the act of measurement produces unavoidable perturbation (also called “back-action”) on the state of the measured system. This effect is, in many cases, not desirable, as back-action often limits the precision of […]
Single photon emitter takes a step closer to quantum tech
Developing non-classical light sources that can emit, on-demand, exactly one photon at a time is one of the main requirements of quantum technologies. But although the first demonstration of such a “single photon emitter”, or […]
LIGENTEC opens R&D Centre in France
Lausanne, Switzerland and Corbeil-Essones, France – April 27, 2022 LIGENTEC SA, the leading supplier of high performance, low loss, silicon nitride Photonic Integrated Circuits established a R&D Centre in France. Photonic integrated circuits (PICs) are […]
The side effects of quantum error correction and how to cope with them
It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results — and […]
Terra Quantum extends Series A funding round to $75M
Terra Quantum AG announces that it has extended its Series A funding round to $75m, as well as its research offering a ground-breaking solution to the longstanding challenge of efficient power devices for nanoelectronics. Terra Quantum […]
Q-CTRL partners with Paul Scherrer Institute to support the scale-up of Quantum Computers
Q-CTRL has announced a partnership with The Paul Scherrer Institute (PSI), Switzerland’s largest research institute for natural and engineering sciences, to pioneer R&D in the scale-up of quantum computers. The strategic partnership will leverage Q-CTRL […]
Hot spin qubits in silicon transistors
A research group at the University of Basel, working with the IBM Research Laboratory, has made a breakthrough in qubits scalability. In classic computers, the solution to the scalability problem lay in silicon chips, which […]
New world record for qubit storage
A UNIGE team in Geneva, Switzerland, has succeeded in storing a quantum bit for 20 milliseconds. A duration that had never before been achieved by a solid-state quantum memory. Long-duration quantum memories for photonic qubits […]
New world record for qubit storage
Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There […]
