Gaussian entanglement and quantum communication: geodesic optimization and multimode bounds
Hemant K. Mishra, Mark M. Wilde
Loss and noise limit the use of light to distribute entanglement, transmit quantum information, and establish secret keys. Gaussian states have a compact description in terms of me…
Fast Random Compilers for Time-Dependent and Time-Independent Lindbladian Simulation
Youngjin Seo, Dhrumil Patel, Hyukjoon Kwon +1
Randomized product formulas provide simple and flexible methods for quantum simulation. While qDRIFT-type randomized simulation has been extended to Lindbladian dynamics, higher-or…
Limits for molecular spectroscopy from quantum channel discrimination
Anirban Dey, Akib Karim, Pieter Kok +2
Absorption spectroscopy identifies molecules by detecting frequency-dependent optical loss, and its fundamental limit is a quantum channel-discrimination problem. In this work, we…
Improved sample complexity bound for sample-based Lindbladian simulation
Siheon Park, Youngjin Seo, Byeongseon Go +3
We establish improved sample-complexity bounds for sample-based Lindbladian simulation based on the Wave Matrix Lindbladization (WML) algorithm. For a jump operator with dimens…
Quantum principal component analysis without eigenvector recovery
Yewei Yuan, Michele Minervini, Mark M. Wilde +1
Principal component analysis (PCA) is traditionally implemented through a covariance or kernel matrix, leading-eigenvector extraction, and hard rank- projection. These steps can…
Bose-Einstein thermal operators for semidefinite optimization
Michele Minervini, Nana Liu, Mark M. Wilde
We establish that semidefinite programs (SDPs) over the unbounded positive semidefinite cone are mathematically equivalent to thermodynamic systems of independent bosonic modes: th…
Fermi-Dirac machines as quantizations of neurons
Alexander He, Nana Liu, Mark M. Wilde
Fermi-Dirac machines were proposed recently as an approach to solving semidefinite optimization problems on quantum computers. Here, we reinterpret them as canonical quantizations…
Central Limit Theorem for Bosonic Quantum Channels
Hami Mehrabi, Ludovico Lami, Mark M. Wilde
In this paper, we develop an extension of the Central Limit Theorem (CLT) to the setting of bosonic quantum channels. This extension provides a deeper understanding of Gaussian bos…
Onset of superactivation of quantum capacity
Marco Parentin, Bjarne Bergh, Nilanjana Datta +1
Superactivation of quantum capacity is the phenomenon whereby two quantum channels, each with zero quantum capacity, can exhibit a strictly positive capacity when used in tandem. I…
Efficiently Computable Strategies and Limits for Bosonic Channel Discrimination
Zixin Huang, Ludovico Lami, Vishal Singh +1
Discriminating between noisy quantum processes is a central primitive for quantum communication, metrology, and computing. While discrimination limits for finite-dimensional channe…
Fermi-Dirac thermal measurements: A framework for quantum hypothesis testing and semidefinite optimization
Nana Liu, Mark M. Wilde
Quantum measurements are the means by which we recover messages encoded into quantum states. They are at the forefront of quantum hypothesis testing, wherein the goal is to perform…
