Microsoft released the first version of its quantum development kit and a new quantum computing programming language Q# last December. Today, the company has released an update that adds support for quantum development on macOS and Linux. Both the Q# language, and the company’s quantum simulator, will run on these platforms in addition to Windows.

The new release of the simulator is much faster than the first release, with the company saying that it runs four to five times faster, especially on simulations with 20 or more qubits.

The quantum libraries and samples are now available under an open source license—the source to these was previously merely shared—enabling others to modify and extend them. Interoperability with existing libraries is also being improved: Microsoft is working on integrating Python support. On Windows, today’s release includes a preview of the Python integration, which allows Q# programs to call Python code and vice versa.

Careful phasing of a photonic qubit brings light under control https://briefnews.eu/careful-phasing-of-a-photonic-qubit-brings-light-under-control/ https://briefnews.eu/careful-phasing-of-a-photonic-qubit-brings-light-under-control/#respond Thu, 08 Feb 2018 17:09:34 +0000 http://briefnews.eu/careful-phasing-of-a-photonic-qubit-brings-light-under-control/

Enlarge / Splitting photons up into a collection of neighboring frequencies may help with quantum computation. (credit: NIST)

Way back when I started writing for Ars, experimental quantum computing had just started to take off. At the time, the big demonstrations of quantum computation were very simple calculations, performed using single photons as repositories of quantum information. Back then, demonstrating even a single logical gate was a challenge. Light ruled the roost, and charged particles were reduced to the status of not-quantum-enough.

That changed, of course. Now, all the big demonstrations make use of charged particles: little superconducting current loops, rows of ions, or others. Light, it seems, has been reduced to a way of moving qubits between charged particles.

But a recent result shows that there is life left in photon-based quantum computers and that the degree of parallelization available to a photon-based quantum computer will be difficult to beat using other qubit technologies.
