The unitary dependence theory for characterizing quantum circuits and states
Communications Physics, 2023 Most existing quantum algorithms are discovered accidentally or adapted from classical algorithms, and there is the need for a systematic theory to understand and design quantum circuits.

Efficient universal quantum circuits [PDF]
Quantum Information and Computation, 2009 Universal circuits can be viewed as general-purpose simulators for central classes of circuits and can be used to capture the computational power of the circuit class being simulated. We define and construct quantum universal circuits which are efficient and has very little overhead in simulation.

Efficient classical simulation of the approximate quantum Fourier transform
, 2006 We present a method for classically simulating quantum circuits based on the tensor contraction model of Markov and Shi (quant-ph/0511069). Using this method we are able to classically simulate the approximate quantum Fourier transform in polynomial time.

Coherent memory for microwave photons based on long-lived mechanical excitations
npj Quantum Information, 2023 Mechanical resonators, due to their capability to host ultralong-lived phonon modes, are particularly attractive for quantum state storage and as memory elements in conjunction with quantum computing and communication networks.

Quantum-circuit black hole lasers [PDF]
Scientific Reports, 2021 AbstractA black hole laser in analogues of gravity amplifies Hawking radiation, which is unlikely to be measured in real black holes, and makes it observable. There have been proposals to realize such black hole lasers in various systems. However, no progress has been made in electric circuits for a long time, despite their many advantages such as high-

Quantum Circuits with Classical Versus Quantum Control of Causal Order
PRX Quantum, 2021 Quantum supermaps are transformations that map quantum operations to quantum operations. It is known that quantum supermaps which respect a definite, predefined causal order between their input operations correspond to fixed-order quantum circuits, also ...
