The field of experimental quantum communication promises ways of efficient and unconditional secure information exchange in quantum states. The possibility of transferring quantum information forms a cornerstone of the emerging field of quantum communication and […]
Although quantum computers are typically described as devices built with qubits that can be in a superposition of two states at once, it is possible to go further and use qutrits which can be in […]

Quantum 6, 616 (2022). https://doi.org/10.22331/q-2022-01-03-616 A finite-dimensional quantum system is coupled to a bath of oscillators in thermal equilibrium at temperature $T>0$. We show that for fixed, small values of the coupling constant $lambda$, the […]
Quantum 6, 615 (2022). https://doi.org/10.22331/q-2022-01-03-615 We develop a framework to analyze the dynamics of a finite-dimensional quantum system $rm S$ in contact with a reservoir $rm R$. The full, interacting $rm SR$ dynamics is unitary. […]
A new proof has debunked a conspiracy that mathematicians feared might haunt the number line. In doing so, it has given them another set of tools for understanding arithmetic’s fundamental building blocks, the prime numbers. […]
Quantum 6, 614 (2022). https://doi.org/10.22331/q-2022-01-03-614 Let $p$ be an odd prime and let $r$ be the smallest generator of the multiplicative group $mathbb{Z}_p^ast$. We show that there exists a correlation of size $Theta(r^2)$ that self-tests […]
I think it was Albert Einstein who said, “As far as the end-of-year prediction lists refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.” […]
Quantum 6, 613 (2022). https://doi.org/10.22331/q-2022-01-03-613 Most quantum key distribution (QKD) protocols can be classified as either a discrete-variable (DV) protocol or continuous-variable (CV) protocol, based on how classical information is being encoded. We propose a […]
