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…
Collaboration tests new method for protecting quantum networks
Oak Ridge National Laboratory collaborated with commercial utility EPB and the University of Tennessee Chattanooga to develop and test the first transmission of an entangled quantum signal using multiple wavelength…
Quantum breakthrough may lead to sustainable chiral spintronics
Rendering of the tilting of relativistic Dirac cones in the bulk electronic bands of a quasi-two-dimensional (2D) magnetic topological semimetal achieved with insertion of hydrogen that generates tunable low-dissipation chiral…
