We offer a 3.5-years PhD position for a motivated researcher to join our work on adaptive quantum sensing. Our goal is to develop an automatic quantum sensor, based on a single spin in diamond, enhanced […]
Quantum 5, 589 (2021). https://doi.org/10.22331/q-2021-11-25-589 We consider the entanglement marginal problem, which consists of deciding whether a number of reduced density matrices are compatible with an overall separable quantum state. To tackle this problem, we […]
The US is blacklisting about a dozen Chinese groups involved in quantum computing and other advanced technologies, according to The Financial Times. The blacklist is meant to stop the export of technologies that may pose […]
Highlights Zurich Instruments launches the SHFQC, the first qubit controller that can control, readout and perform fast feedback on up to 6 qubits. The SHFQC supports control and readout frequencies up to 8.5 GHz without […]
Quantum 5, 588 (2021). https://doi.org/10.22331/q-2021-11-25-588 Gleason-type theorems for quantum theory allow one to recover the quantum state space by assuming that (i) states consistently assign probabilities to measurement outcomes and that (ii) there is a […]
PRESS RELEASE Zurich, Switzerland, November 25th, 2021 The Zurich Instruments SHFQC Qubit Controller offers a full room-temperature qubit control system for up to 6 superconducting qubits in a single instrument. The SHFQC provides channels for […]
The Export Administration Regulations (EAR) managed by the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce calls for the maintenance of an Entity List. The list identifies entities that have been […]
We wrote last September about Dell’s first step in quantum computing to test a solution that integrates their Dell EMC PowerEdge R740xd with IBM Qiskit quantum emulator. They have now taken a second step to test […]
Researchers have developed highly efficient, on-chip frequency shifters that can convert light in the gigahertz frequency range. The frequency shifters are easily controlled, using continuous and single-tone microwaves. Click to rate this post! [Total: 0 […]
Last month, we presented three puzzles that seemed ordinary enough but contained a numerical twist. Hidden below the surface was the mysterious transcendental number e. Most familiar as the base of natural logarithms, Euler’s number […]
