Optimality of Lindblad unfolding in measurement phase transitions

Michael Kolodrubetz

Entanglement phase transitions in hybrid quantum circuits describe individual quantum trajectories rather than the measurement-averaged ensemble, despite the fact that results of m…

Quantum squeezing and sensing with pseudo anti-parity-time symmetry

Xi-Wang Luo, Chuanwei Zhang, Shengwang Du

The emergence of parity-time () symmetry has greatly enriched our study of symmetry-enabled non-Hermitian physics, but the realization of quantum -symme…

Fast Swapping in a Quantum Multiplier Modelled as a Queuing Network

Evan E. Dobbs, Robert Basmadjian, Alexandru Paler +1

Predicting the optimum SWAP depth of a quantum circuit is useful because it informs the compiler about the amount of necessary optimization. Fast prediction methods will prove esse…

Wavelength conversion for single-photon polarization qubits through continuous variable quantum teleportation

Xi-Wang Luo, Chuanwei Zhang, Irina Novikova +2

A quantum internet connects remote quantum processors that need interact and exchange quantum signals over a long distance through photonic channels. However, these quantum nodes a…

Hybrid entanglement between optical discrete polarizations and continuous quadrature variables

Jianming Wen, Irina Novikova, Chen Qian +2

By coherently combining advantages while largely avoiding limitations of two mainstream platforms, optical hybrid entanglement involving both discrete and continuous variables has…

A QUBO formulation for top- eigencentrality nodes

Prosper D. Akrobotu, Tamsin E. James, Christian F. A. Negre +1

The efficient calculation of the centrality or "hierarchy" of nodes in a network has gained great relevance in recent years due to the generation of large amounts of data. The eige…

Exponential suppression of bit or phase flip errors with repetitive error correction

Zijun Chen, Kevin J. Satzinger, Juan Atalaya +88

Realizing the potential of quantum computing will require achieving sufficiently low logical error rates. Many applications call for error rates in the regime, but state…

Removing leakage-induced correlated errors in superconducting quantum error correction

M. McEwen, D. Kafri, Z. Chen +48

Quantum computing can become scalable through error correction, but logical error rates only decrease with system size when physical errors are sufficiently uncorrelated. During co…

Halving the width of Toffoli based constant modular addition to n+3 qubits

Oumarou Oumarou, Alexandru Paler, Robert Basmadjian

We present an arithmetic circuit performing constant modular addition having depth of Toffoli gates and using a total of qubits. This is an improvement by a…
