Tight bounds on the simultaneous estimation of incompatible parameters
Jasminder S. Sidhu, Yingkai Ouyang, Earl T. Campbell +1
The estimation of multiple parameters in quantum metrology is important for a vast array of applications in quantum information processing. However, the unattainability of fundamen…
Subwavelength quantum imaging with noisy detectors
Cosmo Lupo
It has been recently shown that an interferometric measurement may allow for sub-wavelength resolution of incoherent light. Whereas this holds for noiseless detectors, one could ex…
Towards practical security of continuous-variable quantum key distribution
Cosmo Lupo
Rigorous mathematical proofs of the security of continuous-variable quantum key distribution (CV QKD) have been obtained recently. Unfortunately, these security proofs rely on assu…
Nonlinear quantum optics with trion-polaritons in 2D monolayers: conventional and unconventional photon blockade
O. Kyriienko, D. N. Krizhanovskii, I. A. Shelykh
We study a 2D system of trion-polaritons at the quantum level and demonstrate that for monolayer semiconductors they can exhibit a strongly nonlinear optical response. The effect i…
Compilation by stochastic Hamiltonian sparsification
Yingkai Ouyang, David R. White, Earl T. Campbell
Simulation of quantum chemistry is expected to be a principal application of quantum computing. In quantum simulation, a complicated Hamiltonian describing the dynamics of a quantu…
Instability Zones in the Dynamics of a Quantum Mechanical Quasiperiodic Parametric Oscillator
Subhadip Biswas, Pratyusha Chowdhury, Jayanta K Bhattacharjee
Quasi-periodically driven quantum parametric oscillators have been the subject of several recent investigations. Here we show that for such oscillators, the instability zones of th…
