Quantum 7, 1153 (2023). https://doi.org/10.22331/q-2023-10-24-1153 The promise of high-rate low-density parity check (LDPC) codes to substantially reduce the overhead of fault-tolerant quantum computation depends on constructing efficient, fault-tolerant implementations of logical gates on such codes. […]
Quantum 7, 1152 (2023). https://doi.org/10.22331/q-2023-10-24-1152 We introduce a semidefinite programming algorithm to find the minimal quantum Fisher information compatible with an arbitrary dataset of mean values. This certification task allows one to quantify the resource […]
Quantum 7, 1151 (2023). https://doi.org/10.22331/q-2023-10-24-1151 Spiking neural network is a kind of neuromorphic computing that is believed to improve the level of intelligence and provide advantages for quantum computing. In this work, we address this […]
Insider Brief Atom Computing’s next-generation quantum computing platform will feature a 1,225-site atomic array and populated with 1,180 qubits. This is the first time a company has crossed the 1,000-qubit threshold for a universal gate-based […]
Quantum 7, 1150 (2023). https://doi.org/10.22331/q-2023-10-24-1150 Bell’s theorem states that Local Hidden Variables (LHVs) cannot fully explain the statistics of measurements on some entangled quantum states. It is natural to ask how much supplementary classical communication […]
Quantum 7, 1149 (2023). https://doi.org/10.22331/q-2023-10-24-1149 We analyze the amount of classical communication required to reproduce the statistics of local projective measurements on a general pair of entangled qubits, $|Psi_{AB}rangle=sqrt{p} |00rangle+sqrt{1-p} |11rangle$ (with $1/2leq p leq […]
The brain is an exceptionally powerful computing machine. Scientists have long tried to recreate its inner workings in mechanical minds. A team from IBM may have cracked the code with NorthPole, a fully digital chip […]
Insider Brief Deloitte’s Quantum Climate Challenge’s dual role helps tackle climate-related challenges while developing quantum ecosystems. This year, the challenge winner EcoQult used quantum computing to explore new approaches to carbon dioxide capture. In addition […]
Insider Brief QuEra received two grants from Defense Advanced Research Projects Agency (DARPA). Five of the company’s partners also received DARPA IMPAQT grants for their projects conducted on QuEra neutral atom-based quantum computers. The DARPA […]
Applications are invited for Postdoc positions in Quantum Optics, working on the theory of hybrid quantum systems; optomechanical systems, color centers in solids, and superconducting circuits. The successful candidates will work primarily in Mehdi Abdi’s […]
