Quantum 6, 712 (2022). https://doi.org/10.22331/q-2022-05-13-712 We identify time-optimal laser pulses to implement the controlled-Z gate and its three qubit generalization, the C$_2$Z gate, for Rydberg atoms in the blockade regime. Pulses are optimized using a […]
Quantum 6, 711 (2022). https://doi.org/10.22331/q-2022-05-13-711 Quantum low-density parity-check (LDPC) codes are an important class of quantum error correcting codes. In such codes, each qubit only affects a constant number of syndrome bits, and each syndrome […]
While many individuals believe that the possibilities of quantum technology are not yet here, Christine Johnson, CEO of Ingenii, doesn’t believe so. Her company’s quantum data platform was designed to help data scientists use quantum […]
The Quantum Enigmas video series created and produced by Institut quantique (IQ) uses classic enigmas and shows how to solve these using a quantum computer. Even though there is no quantum advantage in the first […]
Future quantum computers are expected not only to solve particularly tricky computing tasks, but also to be connected to a network for the secure exchange of data. In principle, quantum gates could be used for […]
What We offer several postdoctoral research positions in quantum information theory. Potential research topics include the following: Quantum communications theory: capacities of quantum channels and networks, distillation protocols, etc. Theory of quantum key distribution or other […]
D-Wave has been continuously improving its Constrained Quadratic Model (CQM) Hybrid Solver to make it easlier for end users to use and to allow them to developer programs faster that will run on their quantum […]
We have a trio of news items to report on IonQ. The first is an announcement that IonQ is making native gate access available to researchers and developers for both their previous generation 11 qubit […]
Classiq has announced a coding competition with four different quantum programming problems designed to challenge programmers to create circuits that satisfy the problem using either the fewest gate levels or the fewest number of two […]
A quantum system with only 51 charged atoms can take on more than two quadrillion different states. Calculating the system’s behavior is child’s play for a quantum simulator. But verifying the result is almost impossible, […]
