A team of scientists from QuEra Computing, Harvard University and the Massachusetts Institute of Technology has reported the first experimental demonstration of magic state distillation carried out ...

Their strontium-based neutral atom machine is a more restricted kind of quantum computer known as a quantum simulator: while they can excite atoms up to the Rydberg state and create entangled ...

The model has been superseded since Niels Bohr first proposed it in 1913, as our understanding of the quantum world advanced. Erwin Schroedinger proposed a new atomic model that dispensed with ...

Understanding and harnessing them is one of the major challenges for the development of quantum technologies. ... So, when an atom in a crystal lattice array is prepared in the excited state, ...

The Bohr model is a neat but quite imperfect depiction of the inner workings of an atom before things got too muddled up by quantum principles.

This makes quantum computers natural candidates for simulating chemistry. Until now, quantum devices have only been able to calculate unchanging things, such as the energies of molecules. Our study, ...

Quantum computing engineers at UNSW Sydney have shown they can encode quantum information—the special data in a quantum computer—in four unique ways within a single atom, inside a silicon chip ...

Users will be able to run calculations on Pasqal's 100-qubit QPU with a pay-as-you-go model. Pasqal's quantum computer uses neutral-atom technology and offers a range of analog quantum computational ...

Meanwhile, the Model H2 has great specs: 56 fully connected qubits, a single-qubit gate fidelity of 99.99%, a two-qubit gate fidelity of 99.87% and a quantum volume of 2,097,152.
