Multi-Gbps quantum randomness source based on direct detection and vacuum states
Dino Solar Nikolic, Cosmo Lupo, Runjia Zhang +3
Quantum random number generators (QRNGs) based on quadrature measurements of the vacuum have so far used balanced homodyne detection to obtain a source of high entropy. Here we pro…
Error filtration for quantum sensing via interferometry
Zixin Huang, Cosmo Lupo
Dephasing is a main noise mechanism that afflicts quantum information, it reduces visibility, and destroys coherence and entanglement. Therefore, it must be reduced, mitigated, and…
Single-photon sub-Rayleigh precision measurements of a pair of incoherent sources of unequal intensity
Luigi Santamaria Amato, Fabrizio Sgobba, Cosmo Lupo
Interferometric methods have been recently investigated to achieve sub-Rayleigh imaging and precision measurements of faint incoherent sources up to the ultimate quantum limit. Her…
Information theoretical perspective on the method of Entanglement Witnesses
Paulo J. Cavalcanti, Giovanni Scala, Antonio Mandarino +1
We frame entanglement detection as a problem of random variable inference to introduce a quantitative method to measure and understand whether entanglement witnesses lead to an eff…
Comparing metrics for mixed quantum states: Sjoqvist and Bures
Paul M. Alsing, Carlo Cafaro, Orlando Luongo +3
It is known that there are infinitely many distinguishability metrics for mixed quantum states. This freedom, in turn, leads to metric-dependent interpretations of physically meani…
Dynamical quantum phase transitions of the Schwinger model: real-time dynamics on IBM Quantum
Domenico Pomarico, Leonardo Cosmai, Paolo Facchi +3
Simulating real-time dynamics of gauge theories represents a paradigmatic use case to test the hardware capabilities of a quantum computer, since it can involve non-trivial input s…
Error-tolerant oblivious transfer in the noisy-storage model
Cosmo Lupo, James T. Peat, Erika Andersson +1
The noisy-storage model of quantum cryptography allows for information-theoretically secure two-party computation based on the assumption that a cheating user has at most access to…
