Quantum 8, 1409 (2024). https://doi.org/10.22331/q-2024-07-15-1409 Digital quantum simulation has broad applications in approximating unitary evolution of Hamiltonians. In practice, many simulation tasks for quantum systems focus on quantum states in the low-energy subspace instead of […]
Sometimes mathematicians try to tackle a problem head on, and sometimes they come at it sideways. That’s especially true when the mathematical stakes are high, as with the Riemann hypothesis, whose solution comes with a […]
A study in Nature Physics introduces a novel method for generating quantum entanglement using a quantum dot, which violates the Bell inequality. This ultra-low power method could pave the way for scalable and efficient quantum […]
Insider Brief Qubit relaxation time of T1= 0.964 +- 0.092 milliseconds and dephasing time T2 echo 1.155 +- 0.188 milliseconds. Two-qubit gates with a record fidelity reaching 99.9% IQM’s in-house chip fabrication has reached […]
Insider Brief The IEEE Information Theory Society announced that Peter Shor is the recipient of the 2025 Claude E. Shannon Award. The award recognizes Shor’s consistent and profound contributions to the field of information theory. […]
Jeremy O’Brien, CEO of PsiQuantum, is developing the world’s first utility-scale, fault-tolerant quantum computer. At the Third Annual Commercialising Quantum Global event hosted by The Economist, O’Brien discussed quantum computing, detailing the path PsiQuantum is […]
It is the duty of good people, always and everywhere, to condemn, reject, and disavow the use of political violence. Even or especially when evildoers would celebrate the use of political violence against us. It […]
Infleqtion has announced it has sold its super accurate Tiqker quantum clock to the University of Strathclyde in the UK. Tiqker is a cold-atom rubidium based atomic clock that provides long term frequency stability of […]
Insider Brief Researchers unveiled a new type of quantum sensor that they report leverages quantum entanglement to perform detections that “travel back in time.” Kater Murch, Charles M. Hohenberg Professor of Physics and Director of […]
“The Superposition Guy’s Podcast”, hosted by Yuval Boger, CCO at QuEra Computing Lon Hintze, Clayton Crocker, John Dorighi, and Philip Krantz from Keysight, are interviewed by Yuval Boger. They discuss their comprehensive support for quantum […]
