Although quantum technology has proven valuable for highly precise timekeeping, making these technologies practical for use in a variety of environments is still a key challenge. In an important step toward portable quantum devices, researchers have developed a new high-flux and compact cold-atom sour...
A high-flux and compact cold-atom source with low power consumption developed by an Oxford University-led research group is poised to enable devices such as space-based atomic clocks, improving quantum applications for communication and navigation. The research is a step toward portable quantum ...
The quantum frontier: cold atoms in space16 December 2021 Prospects for space-borne cold-atom experiments include the detection of gravitational waves, probes of the equivalence principle and searches for dark matter. Image credits: Physics 5 26 & arXiv:2108.02468 Cold atoms offer exciting ...
Tuning the Topological $heta$-Angle in Cold-Atom Quantum Simulators of Gauge Theories The topological heta heta -angle in gauge theories engenders a series of fundamental phenomena, including violations of charge-parity (CP) symmetry, dynamical topological transitions, and confinement--deconfinement ...
Qiskit Cold Atom Qiskit is an open-source SDK for working with quantum computers at the level of circuits, algorithms, and application modules. This project builds on this functionality to describe programmable quantum simulators of trapped cold atoms in a gate- and circuit-based framework. This ...
up with the laws of quantum physics, which describe behaviors of small objects like atoms. Scientists have already experimented with atom interferometers on Earth to see if the equivalence principle holds true at atomic scales, but they can test it more precisely in space at the Cold Atom Lab....
Quantum computing has several functions: Technology: to beat Moore’s law, limited when devices approach single atom levels Computer science: compute problems with new complexity classes, e.g. in encryption which currently relies on the complexity of splitting integers into its prime number factors ...
Using these manufacturing methods has allowed for the miniaturisation of quantum technologies such as integrated atom chip based systems13,14. An emerging technology capable of allowing further miniaturisation of cold atom based sensors is additive manufacturing, such as 3D-printing. The freedom of ...
