* The silicon-wire arrays absorb up to 96 percent of incident sunlight at a single wavelength and 85 percent of total collectible sunlight * the wires have a near-perfect internal quantum efficiency. * Each wire measures between 30 and 100 microns in length and only 1 micron in diameter.
This is an important proof-of-possibility for silicon qubits because it adds substantial flexibility in how to wire those qubits and how to lay them out geometrically in future silicon-based ''quantum microchips.''" The communiion between two distant silicon-based
The tiniest silicon conducting wire ever made takes us a step closer to the creation of a practical quantum computer. Developed by UNSW PhD student Bent Weber, the wire is 10,000 times thinner than a human hair. Flip-flop qubits: a whole new quantum

We propose a hybrid silicon waveguide scheme to avoid the impact of noise photons induced by pump lights in appliion scenarios of quantum photonic circuits with quantum light sources. The scheme is composed of strip waveguide and shallow-ridge waveguide structures. It utilizes the difference of biphoton spectra generated by spontaneous four-wave mixing (SFWM) in these two waveguides. By

With silicon wire, quantum computers closer to reality World’s thinnest silicon wire, which is just one atom tall and four atoms wide, may play a vital role in developing quantum computers in future. Washington: World’s thinnest silicon wire, which is just one atom
It is worth mentioning that quantum dots based on Si/SiO 2 and SOI technology are both CMOS compatible and in this article we denote the former as silicon MOS and the latter as SOI for clarity. On the heels of the proposal for quantum-dot-based electron spins, Bruce Kane [ 29 ] showed that the nuclear spin of a single 31 P donor in silicon can also be controlled as a qubit.

When the model is applied to a gated quantum wire transistor structure under bias, we find that the stering due to phonons causes the electrons to ster to higher subbands than previously available during simple ballistic transport, with the result that the

Silicon spin qubits have several advantages over superconducting qubits. The silicon spin qubits retain their quantum state longer than competing qubit technologies. The widespread use of silicon
Small-diameter (1 to 7 nanometers) silicon nanowires (SiNWs) were prepared, and their surfaces were removed of oxide and terminated with hydrogen by a hydrofluoric acid dip. Scanning tunneling microscopy (STM) of these SiNWs, performed both in air and in ultrahigh vacuum, revealed atomically resolved images that can be interpreted as hydrogen-terminated Si (111)-(1 × 1) and Si (001)-(1 × 1
In the quantum system of Si nanowire (NW), the energy bandgap obviously increases with decreasing radius size of NW, in which the quantum confinement (QC) effect plays a main role. Furthermore, the simulation result demonstrated that the direct bandgap can be obtained as the NW diameter is smaller than 3 nm in Si NW with (001) direction. However, it is discovered in the simulating calculation
