The construction of quantum circuits to simulate Hamiltonian evolution is central to many
quantum algorithms. State-of-the-art circuits are based on oracles whose implementation is …

Ideal photonic quantum memories can store arbitrary pulses of light with unit efficiency. This
requires operating in the adiabatic regime, where pulses have a duration much longer than …

Neutral atoms are among the leading platforms toward realizing fault-tolerant quantum
computation (FTQC). However, scaling up a single neutral-atom device beyond $\sim 10^ 4 …

The qubit scalability imposes a paramount challenge in the field of quantum computing.
Photonic interconnects between distinct quantum computing modules provide a solution to …

We propose a scheme for generating a high-purity single photon on the basis of cavity
quantum electrodynamics (QED). This scheme employs a four-level system including two …

Restrictions imposed by existing infrastructure can make it hard to ensure an even spacing
between the nodes of future fiber-based quantum networks. We here investigate the …

We propose the use of collective states of matter as a resource for the deterministic
generation of quantum states of light, which are fundamental for quantum information …

We develop methods to find the limits to finite-time single photon extraction from emitter-
cavity systems. We first establish analytic upper and lower bounds on the maximum …

We propose a method for generating optical cat states in propagating pulses based on
cavity quantum electrodynamics (QED). This scheme uses multiple four-level systems …

Cavity-mediated adiabatic transfer (CMAT) is a robust way to perform a two-qubit gate
between trapped atoms inside an optical cavity. In a previous study by Goto and Ichimura [H …
