Researchers from QuTech improved the so-called “Andreev spin qubit” in a critical way and believe it can become a prime candidate in the pursuit of a perfect qubit. The new type of qubit is created […]
Oliver Dial, Quantum CTO at IBM, is interviewed by Yuval Boger. Oliver and Yuval talk about what computer they recommend to each customer, whether the machines get better over time, why customers sometimes choose to […]
Insider Brief Quantum Computing Inc.’s board of directors approved a letter-of-intent to by millionways, an AI firm. millionways develops AI algorithms to effectively provide next-gen feedback to users on their emotional state and personality insights. […]
How far along are the quantum technologies? And what do we really mean when we use the word quantum? Senior Adviser Ulrich Busk Hoff has been conducting research into and communicating about quantum physics for […]
How do brains learn? It’s a mystery, one that applies both to the spongy organs in our skulls and to their digital counterparts in our machines. Even though artificial neural networks (ANNs) are built from […]
Chiral spin liquids are one of the most fascinating phases of matter ever imagined by physicists. These exotic liquids exhibit quasi-particles known as non-Abelian anyons that are neither bosons nor fermions, and whose manipulation could […]
Quantum 7, 1012 (2023). https://doi.org/10.22331/q-2023-05-22-1012 Metric adjusted skew information, induced from quantum Fisher information, is a well-known family of resource measures in the resource theory of asymmetry. However, its asymptotic rates are not valid asymmetry […]
Quantum 7, 1011 (2023). https://doi.org/10.22331/q-2023-05-22-1011 We introduce a classical algorithm to approximate the free energy of local, translation-invariant, one-dimensional quantum systems in the thermodynamic limit of infinite chain size. While the ground state problem (i.e., […]
Quantum 7, 1010 (2023). https://doi.org/10.22331/q-2023-05-22-1010 Communication complexity is the amount of communication needed to compute a function when the function inputs are distributed over multiple parties. In its simplest form, one-way communication complexity, Alice and […]
Quantum 7, 1009 (2023). https://doi.org/10.22331/q-2023-05-22-1009 We introduce a new framework for contextuality based on simplicial sets, combinatorial models of topological spaces that play a prominent role in modern homotopy theory. Our approach extends measurement scenarios […]
