FUJITSU CONNECTED TECHNOLOGIESDigital annealing will be introduced next year芯片DAU芯片，Can provide up to 8,192 bits of computing power，Daus-only computing systems will also be available in fiscal year 2019 (the first half of 2020)，The goal is to provide large-scale parallel processing capacity up to 1 million bits， That is, you can quickly figure out the best solution for a polynomial square with up to a million variables。

Don't wait for quantum computers to become commercially available，Fujitsu President Tatsuka Tanaka at the 2018 Tokyo Forum，Published the world's first commercial chip inspired by quantum annealing algorithm called DAU (Digital Annealer Unit)，Also announced the official launch of digital annealing cloud service from May 15，Let enterprises use cloud services first，To solve the past unwieldy super-complex combinatorial problems，For example, to find the best combination of chemical molecular structure, to optimize the investment strategy of a large number of investment targets, and to optimize the supply path of a small number of diversified production materials in a factory，Fujitsu, for example, has used optimisation of assembly operations in its own factories，To shorten the route for the feeder truck to pick up goods from the huge parts warehouse，To speed up the feeding speed。 Fujitsu actually exhibited the digital annealing chip, which will be launched next year, at the Tokyo Forum。

According to Shigi Sasaki, president of Fujitsu Research Institute, DAU is a dedicated chip that can be used to solve large-scale block optimization, unlike other dedicated processors。

For example, in the development of a new drug, a chemical combination of 50 atoms, 10 to the 48th power, would take 10 to the 24th power of years to solve with current general-purpose computer technology, an almost impossible problem。 But DAU is a dedicated chip designed to solve this kind of super-complex combinatorial optimization, and you can get the answer quickly。

As early as 2015，Fujitsu has teamed up with Ali Sheikholeslami, a professor of computer engineering at the University of Toronto, to develop digital annealing technology，And quantum computer startup 1QBit，Deploy quantum annealing software on Fujitsu cloud service，To launch the first digital annealing cloud service this year ，Can be used to deal with very large scale chunking problems at 1024 bit level (meaning computable up to 1,024 variables polynomial square program)。

Fujitsu AI base disk business director Yoshizawa Naoko said，DAU chips are expected to be available next year，Can further provide up to 8,192位，Accuracy up to 64 bits (up to 1845 bytes)，Daus-only computing systems will also be available in fiscal year 2019 (the first half of 2020)， The goal is to provide large-scale parallel processing capacity up to 1 million bits，That is, you can quickly compute the best solution for a polynomial square program with up to a million variables。



A bit in a traditional computer can have either zero (none) or one (one)，But a bit in a quantum computer can store much larger values (up to 65535, for example)，This allows quantum computers to perform calculations using only a few bits at a time，You can do super complicated math problems， It can be many times faster than a conventional computer，And the more complex，The more variables the math calculates，The faster a quantum computer can process it。

But since quantum computers were still only laboratory products (they even had to operate at very low temperatures), scientists later used the principle of metal annealing to simulate the effect of storing large numbers of values in a single bit in quantum computing, known as quantum annealing。 D-wave Two, a quantum computer Google built in collaboration with NASA in 2013 (using d-Wave technology, another quantum computer innovation)，It's using traditional computer technology，To provide quantum annealing calculations.，In recent years, Google has invested heavily in quantum processors that provide qubit computing，For example, a 72-qubit quantum processor was announced in March。

Fujitsu's DAU, which is based on traditional computer chip technology, is a quantum annealing processor called the Digital Annealing chip, which can provide 8,192 bits, far higher than the 72 qubits Google is building in its lab, and Fujitsu expects to commercialize DAU chips next year。
