A new approach developed by researchers at MIT could provide a significant step forward in quantum error correction. [31] EU-funded scientists have succeeded in redefining the ampere in terms of fundamental constants of physics. [30] Tarucha, the leader of the team, says, "This is a very exciting finding, as it could potentially help to accelerate research into scaling up semiconductor quantum computers, allowing us to solve scientific problems that are very tough on conventional computer systems." [29] Physicists at Saarland University in Saarbrücken, Germany, have succeeded in entangling a single atom with a single photon in the telecom wavelength range. [28] A team of physicists from ICTP-Trieste and IQOQI-Innsbruck has come up with a surprisingly simple idea to investigate quantum entanglement of many particles. [27] For the first time, physicists have experimentally demonstrated ternary-rather than binary-quantum correlations between entangled objects.
