Continuous thermomajorization and a complete set of laws for Markovian thermal processes
Matteo Lostaglio, Kamil Korzekwa
The standard dynamical approach to quantum thermodynamics is based on Markovian master equations describing the thermalization of a system weakly coupled to a large environment, an…
Near-Optimal Quantum Algorithms for Multivariate Mean Estimation
Arjan Cornelissen, Yassine Hamoudi, Sofiene Jerbi
We propose the first near-optimal quantum algorithm for estimating in Euclidean norm the mean of a vector-valued random variable with finite mean and covariance. Our result aims at…
General stabilizer approach for constructing highly entangled graph states
Zahra Raissi, Adam Burchardt, Edwin Barnes
Highly entangled multipartite states such as k-uniform (k-UNI) and absolutely maximally entangled (AME) states serve as critical resources in quantum networking and other quantum i…
No second law of entanglement manipulation after all
Ludovico Lami, Bartosz Regula
Many fruitful analogies have emerged between the theories of quantum entanglement and thermodynamics, motivating the pursuit of an axiomatic description of entanglement akin to the…
Local simultaneous state discrimination
Christian Majenz, Maris Ozols, Christian Schaffner +1
Quantum state discrimination is one of the most fundamental problems studied in quantum information theory. Applications range from channel coding to metrology and cryptography. In…
Estimating gate-set properties from random sequences
J. Helsen, M. Ioannou, J. Kitzinger +4
With quantum computing devices increasing in scale and complexity, there is a growing need for tools that obtain precise diagnostic information about quantum operations. However, c…
