As Moore’s Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as “lightwave electronics” could be […]

Nearly three billion years ago, oceanic mats of cyanobacteria, called blue-green algae, transformed Earth’s atmosphere by converting carbon dioxide into the oxygen we complex animals breath. In their time on the planet, they’ve survived five […]
Quantum 6, 716 (2022). https://doi.org/10.22331/q-2022-05-19-716 Certification of quantum devices received from unknown providers is a primary requirement before utilizing the devices for any information processing task. Here, we establish a protocol for certification of a […]
Quantum 6, 715 (2022). https://doi.org/10.22331/q-2022-05-19-715 Entanglement distillation is an essential building block in quantum communication protocols. Here, we study the class of near-term implementable distillation protocols that use bilocal Clifford operations followed by a single […]
Quantum 6, 714 (2022). https://doi.org/10.22331/q-2022-05-17-714 Neural networks have emerged as a powerful way to approach many practical problems in quantum physics. In this work, we illustrate the power of deep learning to predict the dynamics […]
Quantum 6, 713 (2022). https://doi.org/10.22331/q-2022-05-16-713 We describe a general approach to modeling rational decision-making agents who adopt either quantum or classical mechanics based on the Quantum Bayesian (QBist) approach to quantum theory. With the additional […]
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 […]
Quantum 6, 710 (2022). https://doi.org/10.22331/q-2022-05-11-710 In this work we propose a novel numerical approach to decompose general quantum programs in terms of single- and two-qubit quantum gates with a $CNOT$ gate count very close to […]
Quantum 6, 709 (2022). https://doi.org/10.22331/q-2022-05-09-709 We introduce a new open-source software library $Jet$, which uses task-based parallelism to obtain speed-ups in classical tensor-network simulations of quantum circuits. These speed-ups result from i) the increased parallelism […]
