Insider Brief Rydberg blockade mechanism in these optical lattices give rise to the high precision of experimental quantum control, but, on the other hand, they enforce the constraints on modelling the system. Researchers developed a […]
The University of Alicante Quantum Chemistry group has predicted and published the existence of a new natural phenomenon in matter-radiation interaction, which has recently been experimentally confirmed. This finding is the subject of the review […]
Molecules could make useful systems for quantum computers, but they must contain individually addressable, interacting quantum bit centers. In the journal Angewandte Chemie, a team of researchers has now presented a molecular model with three […]
Using existing experimental and computational resources, a multi-institutional team has developed an effective method for measuring high-dimensional qudits encoded in quantum frequency combs, which are a type of photon source, on a single optical chip. […]
Quantum 6, 840 (2022). https://doi.org/10.22331/q-2022-10-13-840 In contrast to interacting systems, the ground state of free systems has a highly ordered pattern of quantum correlations, as witnessed by Wick’s decomposition. Here, we quantify the effect of […]
Quantum 6, 839 (2022). https://doi.org/10.22331/q-2022-10-13-839 We consider the problem of entanglement-assisted one-shot classical communication. In the zero-error regime, entanglement can increase the one-shot zero-error capacity of a family of classical channels following the strategy of […]
An experimental Postdoctoral Research Associate (PDRA) position based at the National Physical Laboratory is available via the EPSRC’s Quantum Technologies Hub in Quantum Communications. The successful candidate will officially be employed by the University of […]
Quantum 6, 838 (2022). https://doi.org/10.22331/q-2022-10-13-838 Outcome probability estimation via classical methods is an important task for validating quantum computing devices. Outcome probabilities of any quantum circuit can be estimated using Monte Carlo sampling, where the […]
When Daniel Larsen was in middle school, he started designing crossword puzzles. He had to layer the hobby on top of his other interests: chess, programming, piano, violin. He twice qualified for the Scripps National […]
Researchers from Arizona State University and Zhejiang University in China, along with two theorists from the United Kingdom, have been able to demonstrate for the first time that large numbers of quantum bits, or qubits, […]
