This morning Xavier Waintal, coauthor of the new arXiv preprint “””refuting””” Grover’s algorithm, which I dismantled here yesterday, emailed me a two-paragraph response. He remarked that the “classy” thing for me to do would be […]
Insider Brief D-Wave received notice from the New York Stock Exchange (NYSE) that it is not in compliance with the NTSE’s regulations on closing prices. If D-Wave cannot comply with the closing price standard it […]
The W boson, a fundamental particle that carries the charged weak force, is the subject of a new precision measurement of its mass by the ATLAS experiment at CERN. Click to rate this post! [Total: […]
Insider Brief: Ericsson Canada has announced its first two collaborations with the University of Ottawa and the Université de Sherbrooke. The research projects aim to explore quantum-based algorithms for acceleration of processing in telecom networks […]
Quantum 7, 961 (2023). https://doi.org/10.22331/q-2023-03-23-961 We demonstrate an information erasure protocol that resets $N$ qubits at once. The method displays exceptional performances in terms of energy cost (it operates nearly at Landauer energy cost $kT […]
Quantum 7, 960 (2023). https://doi.org/10.22331/q-2023-03-23-960 The fidelity susceptibility is a tool for studying quantum phase transitions in the Hermitian condensed matter systems. Recently, it has been generalized with the biorthogonal basis for the non-Hermitian quantum […]
In January 2022, a small team of physicists watched breathlessly as data streamed out of Google’s quantum computer, Sycamore. A sharp peak indicated that their experiment had succeeded. They had mixed one unit of quantum […]
Quantum 7, 959 (2023). https://doi.org/10.22331/q-2023-03-23-959 One of the challenges of quantum computers in the near- and mid- term is the limited number of qubits we can use for computations. Finding methods that achieve useful quantum […]
The idea of a multiverse consisting of “parallel universes” is a popular science fiction trope, recently explored in the Oscar-winning movie “Everything Everywhere All At Once.” However, it is within the realm of scientific possibility. […]
Palacky University Olomouc, Czech Republic, announces the opening a 1+1-year position for a post-doctoral researcher in the theory of multi-user continuous-variable quantum communication within an EU-funded project in the quantum communication team led by Dr. […]
