Insider Brief Bristol and London-based quantum algorithms startup Phasecraft has won a UK government contract to explore using quantum computing to optimise energy grids as part of the Quantum Catalyst Fund. Phasecraft’s contract is one […]
Topological wave structures are wave patterns that exhibit specific topological properties, or in other words, properties that remain unvaried under smooth deformations of a physical system. These structures, such as vortices and skyrmions, have attracted […]
A postdoc position is available in the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge, in the group of Hamza Fawzi. The position is on the applications of convex relaxations […]
Quantum 8, 1267 (2024). https://doi.org/10.22331/q-2024-02-27-1267 Naive attempts to put together relativity and quantum measurements lead to signaling between space-like separated regions. In QFT, these are known as $textit{impossible measurements}$. We show that the same problem […]
Insider Brief “Fractional charge,” is exceedingly rare, and if it can be controlled, it could help to build resilient, fault-tolerant quantum computers. MIT physicists have observed the elusive fractional charge effect in five layers of […]
For years, niobium was considered an underperformer when it came to superconducting qubits. Now, scientists supported by Q-NEXT have found a way to engineer a high-performing niobium-based qubit and take advantage of niobium’s superior qualities. […]
Measuring the properties of light: Scientists realize new method for determining quantum states0 (0)
Scientists at Paderborn University have used a new method to determine the characteristics of optical quantum states. For the first time, they are using certain photon detectors—devices that can detect individual light particles—for so-called homodyne […]
It is a truth of both physics and everyday experience that things fall apart. Ice melts. Buildings crumble. Any object, if you wait long enough, gets mixed up with itself and its surroundings beyond recognition. […]
Quantum 8, 1266 (2024). https://doi.org/10.22331/q-2024-02-26-1266 Quantum metrology allows for measuring properties of a quantum system at the optimal Heisenberg limit. However, when the relevant quantum states are prepared using digital Hamiltonian simulation, the accrued algorithmic […]
Insider Brief Xanadu receives $3.75 million CAD through the Regional Quantum Initiative to accelerate the development of quantum software for practical applications. The repayable contribution is aimed at helping companies advance and commercialize their quantum […]
