Black holes really are giant fuzzballs, a new study says. The study attempts to put to rest the debate over Stephen Hawking’s famous information paradox, the problem created by Hawking’s conclusion that any data that […]
Fluids can be roughly divided into two categories: regular ones and weird ones. Regular ones, like water and alcohol, act more or less as expected when pumped through pipes or stirred with a spoon. Lurking […]
It’s here, folks, the last edition of Hardware Heroes Changing Quantum Tech. In this week’s offering, we have some great minds working for Zurich Instruments, as well as those working for the big boys […]
NTT Corporation in cooperation with the University of Tokyo and RIKEN has developed an optical fiber-coupled quantum light source, which is a key technology for realizing a fault-tolerant large-scale universal optical quantum computer, according to […]
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. […]
