Combinatorial optimization problems such as these are difficult to solve at high speed and at a reasonable computational cost with existing computers because the number of combinatorial patterns increases exponentially as the scale of the problem grows.<\/p>\n\n\n\n<p>One way to tackle these combinatorial optimization problems is to map them to a binary representation called an Ising model, and then use a specialized optimizer to find the ground state of this Ising system.<\/p>\n\n\n\n<p>Toshiba\u2019s new Simulated Quantum Bifurcation Machine+ (SQBM+) on Azure Quantum, based on its <a href=\"https:\/\/www.global.toshiba\/ww\/products-solutions\/ai-iot\/sbm.html\" target=\"_blank\" rel=\"noreferrer noopener\">Simulated Bifurcation Machine (SBM)<\/a>, is an&nbsp;Ising&nbsp;model solver that can solve complex and large-scale combinatorial optimization problems with up to 100,000 variables at high speed.&nbsp;<\/p>\n\n\n\n<p>Toshiba has adopted a new approach, inspired by their quantum computing research, that significantly improves the speed, accuracy, and scale of their SBM. There are two algorithms available through the SQBM+ provider in Azure Quantum: the high-speed Ballistic Simulated Bifurcation algorithm (bSB) designed to find a good solution in a short time; and the high-accuracy Discrete Simulated Bifurcation algorithm (dSB) <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.abe7953\" target=\"_blank\" rel=\"noreferrer noopener\">which finds more accurate solutions at a calculation speed that surpasses that of other machines<\/a> (both classical and quantum). An auto-tune function has also been implemented that will auto-select which algorithm to use based on the problem submitted. These algorithms are optimized automatically to provide the best performance on GPU hardware deployed in the Azure cloud.<\/p>\n\n\n\n<p>Users can select one of these algorithms specifically, or simply allow the auto selection function to choose on their behalf. This choice is made by supplying values for the &#8220;algo&#8221; and &#8220;auto&#8221; parameters during solver instantiation using the Azure Quantum Python SDK. More information is available in the <a href=\"https:\/\/docs.microsoft.com\/azure\/quantum\/provider-toshiba\" target=\"_blank\" rel=\"noreferrer noopener\">Toshiba SQBM+ provider documentation<\/a>, and a sample showing how to choose between the different algorithm options can be found at the <a href=\"https:\/\/github.com\/microsoft\/qio-samples\/blob\/main\/samples\/toshiba-sqbm.py\" target=\"_blank\" rel=\"noreferrer noopener\">qio-samples repo<\/a>.<\/p>\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/azure.microsoft.com\/en-us\/blog\/quantum\/wp-content\/uploads\/2022\/06\/Picture7.webp\" alt=\"Quantum Development Kit \" class=\"wp-image-9978 webp-format\" srcset=\"\" data-orig-src=\"https:\/\/azure.microsoft.com\/en-us\/blog\/quantum\/wp-content\/uploads\/2022\/06\/Picture7.webp\"><\/figure>\n\n\n\n<p><em>&#8220;The core technology of SQBM+ is SBM, which is software that utilizes currently available computers and achieves high-accuracy approximate solutions for complex and large-scale problems in a short amount of time.
