Trapped Ions Share a Wired Connection

Scientists at the University of California, Berkeley have persuaded two trapped ions to interact over a distance of 620 µm – much larger than would be possible via their intrinsic interaction – by connecting them with a room-temperature wire. This proof-of-principle experiment provides a pathway to more precise measurements of fundamental physics based on long-distance interactions between trapped particles.

UC Berkeley to lead $25 million quantum computing center

As part of the federal government’s effort to speed the development of quantum computers, the National Science Foundation (NSF) has awarded the University of California, Berkeley, $25 million over five years to establish a multi-university institute focused on advancing quantum science and engineering and training a future workforce to build and use quantum computers.

Quantum computer as detector shows space is not squeezed

UC Berkeley physicists used partially entangled atoms identical to the qubits in a quantum computer to demonstrate more precisely than ever before – to one part in a billion billion – that space is uniform in all directions and not squeezed.
