npj Quantum Information, Published online: 26 November 2024; doi:10.1038/s41534-024-00918-6 Quantum computing platforms are subject to contradictory engineering requirements: qubits must be protected from mutual interactions when idling (‘doing nothing’), and strongly interacting when in operation. […]
Light, being massless, casts no shadow; under ordinary circumstances, photons pass right through each other unimpeded. Researchers, in the Department of Physics at uOttawa, along with the Boyd Research Group, have demonstrated a laser beam […]
Researchers from Martin Luther University Halle-Wittenberg (MLU) and the Max Planck Institute of Microstructure Physics in Halle have developed a groundbreaking method to analyze magnetic nanostructures with exceptional precision. This technique achieves a resolution of […]

Erbium (Er) ions are the ideal candidate with environmentally protected […]
npj Quantum Information, Published online: 21 November 2024; doi:10.1038/s41534-024-00899-6 Researchers propose a multi-particle ‘which-path’ gedanken experiment with a quantum detector. Contrary to conventional ‘which-path’ experiments, the detector maintains its quantum state during interactions with the […]
npj Quantum Information, Published online: 21 November 2024; doi:10.1038/s41534-024-00901-1 A central building block of many quantum algorithms is the diagonalization of Pauli operators. Although it is always possible to construct a quantum circuit that simultaneously […]
