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 […]
As the Internet of Things expands, engineers want to embed AI into everything, but the amount of energy it requires is a challenge for the smallest and most remote devices. A new “nanomagnetic” computing approach […]
Quantum 6, 708 (2022). https://doi.org/10.22331/q-2022-05-09-708 We introduce finite-function-encoding (FFE) states which encode arbitrary $d$-valued logic functions, i.e., multivariate functions over the ring of integers modulo $d$, and investigate some of their structural properties. We also […]
