Quantum logic gate lights up

(PhysicsWeb) Physicists in the US have taken another important step towards making a quantum computer. Duncan Steel of the University of Michigan and co-workers have created a logic gate using two electron-hole pairs - also known as "excitons" - in a quantum dot.

Archaeology turns to superconductivity

(PhysicsWeb) Researchers from Israel have developed a new way to date archaeological objects that is based on superconductivity. The new technique relies on measuring the magnetic signal from lead - which was widely used in antiquity - in samples that have been cooled to cryogenic temperatures.

Nuclear physicists confirm element 110 discovery

(Physicsweb) The production of an element that has already been seen in three different laboratories would not normally be newsworthy. However, confirmation that element 110 can be made in collisions between lead and nickel nuclei is noteworthy given the recent scandal over element 118.

Editor Berkeley Lab Physicist Challenges Speed of Gravity Claim

(Berkeley Lab) Albert Einstein may have been right that gravity travels at the same speed as light but, contrary to a claim made earlier this year, the theory has not yet been proven. A scientist at Lawrence Berkeley National Laboratory (Berkeley Lab) says the announcement by two scientists, widely reported this past January, about the speed of gravity was wrong.

Trapped ions make logic gates

(PhysicsWeb) Quantum computing has moved another step forward as two independent research groups report the creation of logic gates using pairs of trapped ions. The scientists - based in the US and Austria - have demonstrated new techniques that involve the quantum control of "entangled" ions.
