Solid-state qubits: Forget about being clean, embrace mess

New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal, and some will form pairs that ...

A promising pairing: Scientists demonstrate new combination of materials for quantum science

Quantum information scientists are always on the hunt for winning combinations of materials, materials that can be manipulated at the molecular level to reliably store and transmit information. Following a recent proof-of-principle ...

Physicists 'entangle' individual molecules for the first time, hastening possibilities for quantum computing

For the first time, a team of Princeton physicists have been able to link together individual molecules into special states that are quantum mechanically "entangled." In these bizarre states, the molecules remain correlated ...

Study finds more stable clocks could measure quantum phenomena, including the presence of dark matter

The practice of keeping time hinges on stable oscillations. In a grandfather clock, the length of a second is marked by a single swing of the pendulum. In a digital watch, the vibrations of a quartz crystal mark much smaller ...

Single ions in nano-sized particles: A new platform for quantum information processing

Processing quantum information relies on interacting qubits—the basic building blocks of quantum information—to perform computational tasks. Scientists are searching for the optimal qubit platform that can perform operations ...

The controllable splitting of a single Cooper pair in a hybrid quantum dot system

Cooper pairs are pairs of electrons in superconducting materials that are bound to each other at low temperatures. These electron pairs are at the root of superconductivity, a state where materials have zero resistance at ...

Optical fiber–based, single-photon light source at room temperature for next-generation quantum processing

Quantum-based systems promise faster computing and stronger encryption for computation and communication systems. These systems can be built on fiber networks involving interconnected nodes which consist of qubits and single-photon ...

New quantum computing architecture achieves electron charge qubit with 0.1 millisecond coherence time

Coherence stands as a pillar of effective communication, whether it is in writing, speaking or information processing. This principle extends to quantum bits, or qubits, the building blocks of quantum computing. A quantum ...

Researchers use measurements to generate quantum entanglement and teleportation

Quantum mechanics is full of weird phenomena, but perhaps none as weird as the role measurement plays in the theory. Since a measurement tends to destroy the "quantumness" of a system, it seems to be the mysterious link between ...

Illuminating errors creates a new paradigm for quantum computing

Researchers have developed a method that can reveal the location of errors in quantum computers, making them up to 10 times easier to correct. This will significantly accelerate progress towards large-scale quantum computers ...
