Quantum Error Correction Will Enable Quantum Telescopes

by

Researchers from Australia and Singapore are working on a new quantum technique that could enhance optical VLBI. It’s known as Stimulated Raman Adiabatic Passage (STIRAP), which allows quantum information to be transferred without losses. When imprinted into a quantum error correction code, this technique could allow for VLBI observations into previously inaccessible wavelengths. Once integrated …

Fundamental Quantum Theorem Applies to Temperatures Beyond Absolute Zero

by

The adiabatic theorem – a fundamental achievement of quantum mechanics – was first formulated by Max Born and Vladimir Fock at the dawn of quantum mechanics. The theorem ensures that the evolving quantum state always remains close the so-called instantaneous eigenstate if external parameters change slowly enough. In a sense, adiabatic evolution is something like …

Interference Noise Shield Extend Quantum Systems To Last 10,000 Times Longer

by

Researchers at the University of Chicago have enabled quantum states to last 10,000 times longer than before. The quantum system was operational for a total of 22 milliseconds, four orders of magnitude greater than if the quantum system was left unshielded. They tuned the magnetic field to the rapid rotation of the electron spins inside …
