22:52 Photonics.comQuantum Dots Create Distance Between Electron Spins for Quantum Computing

Scientists at the Niels Bohr Institute have realized the swap of electron spins between distant quantum dots. This is significant for future quantum communications because it will allow the distance between the quantum dots to be large enough for integration with traditional microelectronics and, perhaps, a future quantum computer. The Copenhagen team collaborated with researchers at Purdue University and the University of Sydney to make the discovery. One method of storing and exchanging quantum information is through electron spin states, where the electrons’ charge and spin is manipulated by gate-voltage pulses. It was believed that this method can only work if quantum dots touch each other. If the dots are squeezed too close together, the spins will react too violently; if placed too far apart, the spins will interact too slowly. Both fast spin exchange and enough room

Time goes in one direction: forward. Little boys become old men but not vice versa; teacups shatter but never spontaneously reassemble. This cruel and immutable property of the universe, called the "arrow of time," is fundamentally a consequence of the second law of thermodynamics, which dictates that systems will always tend to become more disordered over time. But recently, researchers from the U.S. and Russia have bent that arrow just a bit -- at least for subatomic particles.In the new study, published Tuesday (Mar. 12) in the journal Scientific Reports, researchers manipulated the arrow of time using a very tiny quantum computer made of two quantum particles, known as qubits, that performed calculations.

One challenge to making photon-based quantum computing practical is finding a way to manipulate and measure the thousands of qubits that are needed to process extremely large data sets. A multi-institutional research team has now demonstrated a way to map and measure large-scale photonic quantum correlation with single-photon sensitivity. In addition to the new measurement technique, which is called correlation on spatially mapped photon-level image (COSPLI), the researchers also developed a way to detect signals from single photons and their correlations in tens of millions of images. When qubits are photons, their number can be increased by increasing the number of modes encoded in the photonic degrees of freedom,that is, the polarization, frequency, time, and location measured for each photon. This increases the number of qubits without the need to use more photons,

Building a quantum computer requires reckoning with errors—in more than one sense. Quantum bits, or "qubits," which can take on the logical values zero and one simultaneously, and thus carry out calculations faster, are extremely susceptible to perturbations. A possible remedy for this is quantum error correction, which means that each qubit is represented redundantly in several copies, such that errors can be detected and eventually corrected without disturbing the fragile quantum state of the qubit itself. Technically, this is very demanding. However, several years ago, an alternative proposal suggested storing information not in several redundant qubits, but rather in the many oscillatory states of a single quantum harmonic oscillator. The research group of Jonathan Home, professor at the Institute for Quantum Electronics at ETH Zurich, has now realised such a qubit encoded in an

The first type of qubit used for the new system — a single-spin qubit called a Loss-DiVincenzo (LD) qubit — has high control fidelity, which makes it good for calculations.
