Quantum Error Correction Will Enable Quantum Telescopes

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

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

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 …

Quantum Entangled Computer Memory Over 30 Miles Enables Quantum Internet

Chinese scientists have transmitted quantum computer memory between two entangled clouds of atoms over 50 kilometers. They developed an efficient atom-photon entanglement source that is suitable for low-loss transmission in fibers. This means a quantum internet could span a large city network. They entangled two clouds of a billion atoms then extracted a photon from …

Chip-to-chip Quantum Teleportation and Multi-photon Entanglement in silicon

Silicon is a compelling platform for classical optical telecommunications as well as quantum communications, both through optical fibers. In general, the silicon-based integrated quantum transceivers could provide possible low-cost and high-performance secure communication networks. A reliable transfer of single photon qubits from one silicon device to another has already been shown, and the distribution of …
