Quantum computers, which operate leveraging quantum mechanics effects, could soon outperform traditional computers in some advanced optimization and simulation tasks. Most quantum computing systems ...

Quantum researchers have deployed a new algorithm to manage noise in qubits in real time. The method can be applied to a wide range of different qubits, even in large numbers. Noise is the "ghost in ...

Understanding whether quantum gravitational effects can lead to a fundamental decoherence, affecting all systems regardless of their environment, is a long standing open challenge. Here we provide a ...

The need for constant miniaturization of electronic circuits 1,2, increase in problem solving speed 3,4, development of unbreakable codes 5,6, and secure communication 7,8 has made quantum information ...

Scientists have developed a method to extract the spectral density for molecules in solvent using simple resonance Raman experiments -- a method that captures the full complexity of chemical ...

The qubit state decays toward the “north pole” of the sphere due to decoherence. Using the study’s coherence-stabilized sensing protocol, the researchers temporarily counteracted the decay, leading to ...

A research team has identified environmental interactions as the cause of ultrafast electronic decoherence in solids, a long-standing open question in quantum physics. (Nanowerk News) A physics team ...

Devices like lasers and other semiconductor-based technologies operate on the principles of quantum mechanics, but they only scratch the surface. To fully exploit quantum phenomena, scientists are ...

This study demonstrates how integrating decoherence-free subspaces with dynamical decoupling enhances quantum state fidelity, offering a practical route to more noise-resilient quantum computing ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...
