Quantum computing is like Forrest Gump’s box of chocolates: You never know what you’re gonna get. Quantum phenomena—the behavior of matter and energy at the atomic and subatomic levels—are not definite, one thing or another. […]
Quantum 8, 1377 (2024). https://doi.org/10.22331/q-2024-06-17-1377 It is a long-standing open question in quantum complexity theory whether the definition of $non-deterministic$ quantum computation requires quantum witnesses (QMA) or if classical witnesses suffice (QCMA). We make progress […]
Quantum 8, 1376 (2024). https://doi.org/10.22331/q-2024-06-17-1376 We investigate what quantum advantages can be obtained in multipartite non-cooperative games by studying how different types of quantum resources can lead to new Nash equilibria and improve social welfare […]
Quantum 8, 1375 (2024). https://doi.org/10.22331/q-2024-06-17-1375 Efficient synthesis of arbitrary quantum states and unitaries from a universal fault-tolerant gate-set e.g. Clifford+T is a key subroutine in quantum computation. As large quantum algorithms feature many qubits that […]
Insider Brief D-Wave Quantum Inc. announced the launch of a new hybrid quantum solver for nonlinear programs. Available through D-Wave’s Leap quantum cloud service, the company believes the new solver will help customers solve complex […]
We learn in grade school that water freezes at zero degrees Celsius, but that’s seldom true. In clouds, scientists have found supercooled water droplets as chilly as minus 40 C, and in a lab in […]
Quantum 8, 1374 (2024). https://doi.org/10.22331/q-2024-06-17-1374 A semidefinite program (SDP) is a particular kind of convex optimization problem with applications in operations research, combinatorial optimization, quantum information science, and beyond. In this work, we propose variational […]
Quantum 8, 1373 (2024). https://doi.org/10.22331/q-2024-06-17-1373 We consider the classical shadows task for pure states in the setting of both joint and independent measurements. The task is to measure few copies of an unknown pure state […]
The Quantum Insider has been closely following Stephanie Simmons and her company Photonic since its founding. Simmons, a physicist and former researcher at Harvard University, co-founded Photonic with the vision of building distributed quantum computers […]
Quantum Computing Inc. (QCI) received $27.3 thousand in revenue for the period ended March 31, 2024. The bulk of the revenue was due to professional services that utilize the Dirac-series computers and other prototype design […]
