Using a D-Wave quantum-annealing computer as a testbed, scientists at Los Alamos National Laboratory have shown that it is possible to isolate so-called emergent magnetic monopoles, a class of quasiparticles, creating a new approach to […]
PRESS RELEASE — Quantum Computing Inc., a leader in bridging the power of classical and quantum computing, has listed its shares to the Nasdaq Capital Market®. With the opening bell, QCI will become one of […]
Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they’ve found one. In a pair of papers, researchers at the University of Maryland’s (UMD) Quantum […]
Maybe it’s the way we refer to “ecosystems” that make it sound that quantum research hubs are created organically and spontaneously. Quantum ecosystems do not germinate out of the floors of research labs, they are […]
Scientist demonstrated a new way of observing atoms as they move in a tiny quantum electronic switch as it operates. Along the way, they discovered a new material state that could pave the way for […]
Electronic circuits that compute and store information contain millions of tiny switches that control the flow of electric current. A deeper understanding of how these tiny switches work could help researchers push the frontiers of […]
Quantum 5, 505 (2021). https://doi.org/10.22331/q-2021-07-15-505 We study the role of coherence in closed and open quantum batteries. We obtain upper bounds to the work performed or energy exchanged by both closed and open quantum batteries […]
Quantum 5, 504 (2021). https://doi.org/10.22331/q-2021-07-15-504 We introduce $textit{Partially Coherent Direct Sum}$ (PCDS) quantum channels, as a generalization of the already known $textit{Direct Sum}$ quantum channels. We derive necessary and sufficient conditions to identify the subset […]
In October 2018, David Asperó was on holiday in Italy, gazing out a car window as his girlfriend drove them to their bed-and-breakfast, when it came to him: the missing step of what’s now a […]
The Google Quantum AI team has found that adding logical qubits to the company’s quantum computer reduced the logical qubit error rate exponentially. In their paper published in the journal Nature, the group describes their […]
