Quantum engineers ‘squeeze’ laser frequency combs to make more sensitive gas sensors
Frequency comb spectroscopy and quantum noise. Credit: Daniel I. Herman et al For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing…
‘Magic-wavelength optical tweezers’ achieve quantum entanglement of molecules
An illustration of two entangled molecules which are individually trapped in magic-wavelength optical tweezers. Credit: Durham University Researchers at Durham University have successfully demonstrated long-lasting quantum entanglement between molecules, opening…
Scientists achieve direct experimental realization of dual-type entangling gates
Using the same laser setup to entangle dual-type qubits. Credit: Chenxi Wang and Chuanxin Huang. To develop scalable and reliable quantum computers, engineers and physicists will need to devise effective…
Fast control methods enable record-setting fidelity in superconducting qubit
In an artist’s impression of a recent MIT experiment, a central sphere represents a qubit, which is irradiated by two control signals: charge (blue) and flux (purple). These control signals…
Physicists discover and explain unexpected magnetism in atomically thin material
MIT physicists have created an ultrathin, two-dimensional material with unusual magnetic properties. They did so by working with three layers of graphene. Each layer is composed of only a single…
