Bristol University Offers Cloud Access To Quantum Chip

Summary: 

Anyone can try quantum computing experiments on Bristol’s public access two-quibit chip.

Bristol University’s centre for quantum photonics has hooked up its quantum chip to the web. Anyone interested in quantum physics or computing can follow a link to Bristol’s Qcloud and try an experiment on a quantum simulator, before running it on a real quantum computer. Read the whole article at www.techweekeurope.co.uk.

QIPC conference, Florence

Summary: 

The QUIE2T - sponsored international QIPC conference 2013 was successfully staged in Florence last week.

In addition to the scientific program, the 2013 QIPC conference comprised sessions that were of interest beyond the scientific community, and that continued the tradition of similar activities at earlier QIPC conferences. Adjusted to the vocation of QUIE2T, these activities included an ‚Industry Session‘, an ‚EU funding session‘ and the ceremony for the ‚QIPC Young Investigator Award‘.

Quantum dot admittance probed at microwave frequencies with an on-chip resonator

We have investigated the microwave frequency dynamic admittance of a quantum dot tunnel coupled to a two-dimensional electron gas. The measurements are made via a high-quality 6.75 GHz on-chip resonator capacitively coupled to the dot. The resonator frequency is found to shift both down and up close to conductance resonances of the dot corresponding to a change in the reactance of the system from capacitive to inductive (see Fig. 1). The observations are consistently explained in a scattering matrix model.

Demonstrating W-type entanglement of Dicke-states in resonant cavity quantum

One important key characteristics of a non-classical physical system is entanglement. For a system containing three qubits two important classes of entangled states are GHZ- and W-states. The first class consists of superposition states between |000⟩ and |111⟩ and the second one arises when a single excitation is symmetrically shared between three qubits, i.e. in an equal superposition between |001⟩, |010⟩ and |100⟩.

Experimental Monte Carlo quantum process certification

Tomography is the main method used for measuring the fidelity of an experimentally implemented quantum process. However, it is a very inefficient method since the number of measurements as well as the time needed for the data post-processing scale exponentially with the number of qubits. With the ongoing experimental progress and growth in system size, quantum process tomography will soon become infeasible in state-of-the art experiments.
