World’s Most Accurate and Precise Atomic Clock Pushes New Frontiers in Physics
World’s Most Accurate and Precise Atomic Clock Pushes New Frontiers in Physics
In humankind’s ever-ticking pursuit of perfection, scientists have developed an atomic clock that is more precise and accurate than any clock previously created. The new clock was built by researchers at JILA, a joint institution of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.
Japanese Scientists Have Developed a Superconducting Circuit That Can Control Multiple Qubits via a Single Cable
Researchers from the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, collaborating with Yokohama National University, Tohoku University, and NEC Corporation, have proposed and successfully demonstrated a new method that can control multiple qubits via a single cable using microwave multiplexing technology at low temperature. The researchers said that this circuit has the potential to increase the density of microwave signals per cable by approximately 1,000 times, thereby increasing the number of controllable qubits significantly.

An Elegant Method for the Detection of Single Spins Using Photovoltage
An Elegant Method for the Detection of Single Spins Using Photovoltage
Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.
Nuclear Spins Tamed for Quantum Applications
Nuclear Spins Tamed for Quantum Applications
Nuclear spins in a crystal can be detected and manipulated through their interactions with the more accessible electron spin of a neighboring crystal defect. This strategy has enabled nanoscale magnetic resonance imaging and other quantum applications. But a long-standing challenge has been to target a specific nuclear spin, while protecting the delicate quantum nature of the electron spin. Important progress on this challenge has now been achieved by two teams at the Delft University of Technology in the Netherlands.
