A trio of interesting software announcements came out this week and here is a summary of each of them.
Cambridge Quantum Computing (CQC) announced version 0.7 of their t|ket> software platform. The most significant change was not technical but rather they have decided to remove all license restrictions for use of tket’s Python module (known as pytket) making the software free to use. Other improvements include support for Microsoft’s Azure Quantum cloud platform, support for conditional operations available with the Honeywell quantum computer, support for mid-circuit measurement on IBM Quantum devices, substitution of named operations with other operations, boxes or circuits, and improvements in circuit optimization and noise mitigation performance. Additional information is available in a news release on the CQC website here, a Medium article titled Execute Circuits on Azure Quantum using t|ktet>, and a changelog for version 0.7.
Xanadu has released version 0.14.0 of Pennylane, its cross-platform Python library for differentiable programming of quantum computers. This release includes several new features and improvements. In addition, Xanadu also has developed a plug-in to Zapata’s Orquestra software that allows uses of Pennylane to use Orquestra as a backend for simulating and executing quantum circuits. The combination is particularly useful for those who use Pennylane for differentiable programming and run large, batched operations and take advantage of Orquestra’s workflow management capabilities. For more, you can view information on Pennylane release 0.14.0 posted on GitHub here and a blog article that describes the Pennylane-Orquestra integration here.
1QBit has been developing a chemistry simulation platform called QEMIST to provide high-speed, high-accuracy ground state energy simulations using a problem decomposition approach. The software is compatible with both classical and quantum computing backends. In particular, with Microsoft’s announcement that Azure Quantum has started a Public Preview, 1QBit announced it is starting an alpha test program for selected users to use QEMIST on Azure Quantum. A description of QEMIST is available on 1QBit’s website here. There is also a video demonstration that was presented at a recent Azure Quantum Developers Workshop available here (1QBit’s portion starts at time 14:00).
