Quantum Qubit Read‑out Takes Major Power‑Efficiency Leap Researchers in Sweden have created a pulse‑activated microwave amplifier that reduces power usage by a factor of ten while preserving qubit ...

In the journal Physical Review Applied, researchers from the University of Illinois Urbana-Champaign's Grainger College of ...

The work considers a qubit interacting off-resonantly a nonlinear Kerr-like quantum-harmonic-oscillator cavity field through nonlinear intensity-dependent and one-photon interactions. The analytical ...

Understanding randomness is crucial in many fields. From computer science and engineering to cryptography and weather ...

The first being that single qubit quantum clones retain the same Bloch angle as the initial quantum state. This means that if the mixed state of the quantum clone can be computed to high enough ...

Common Sense Media editors help you choose Picture Books with Truly Amazing Illustrations. Dazzling art draws young readers in and helps tell the story.

Quantum computers still face a major hurdle on their pathway to practical use cases: their limited ability to correct the ...

Quantum computing has been accumulating tremendous attention in recent years. In current superconducting quantum processors, each qubit can only be connected with a limited number of neighbors.

Using CCE simulations, we reveal a general scaling relation between the electron spin coherence time and the properties of qubit host materials that enables rapid and quantitative exploration of new ...

This reduces qubit decoherence and lays the foundation for more powerful quantum computers with significantly more qubits and enhanced performance.
