Quantum computers with thousands or millions of qubits will require a scalable solution for qubit control and readout electronics. Colocating these electronics
Open system simulations of quantum transport enable the computational study of true steady states, Floquet states, and the role of temperature, time-dynamics

We outline a proposal to realize Electromagnetically Induced Transparency (EIT) with the potential to store Terahertz (THz) optical pulses in Cesium atoms. Such
Entangled photons produced by parametric down-conversion effectively have two down-conversion paths. Ideally, amplitudes of the two paths are matched.We show
How can two parties with competing interests carry out a fair coin flip, using only a noiseless quantum channel? This problem (quantum weak coin-flipping) was

The performance of superconducting circuits for quantum computing is limited by materials losses. In particular, coherence times are typically bounded by two
Consider a quantum circuit that, when fed a constant input, produces a fixed-length random bit- string in each execution. Executing it many times yields a

We review the rapid recent progress in single-photon sources based on multiplexing multiple probabilistic photon-creation events. Such multiplexing allows
A prominent application of quantum cryptography is the distribution of cryptographic keys that are provably secure. Such security proofs were extended by

The current practice of manually tuning quantum dots (QDs) for qubit operation is a relatively time- consuming procedure that is inherently impractical for
The recognition that large classes of quantum many-body systems have limited - or efficiently representable - entanglement in the ground and low-lying excited
