Improve four performance! D-wave releases next generation quantum annealing prototype

（ picture source ： The Internet ）

In recent days, ,D-Wave Announce the next generation of quantum annealing systems Advantage2 The experimental prototype of has been connected to Leap Quantum cloud services , You can go through Leap Make a commercial visit to it .

according to D-Wave Technology roadmap ,Advantage2 System is its sixth generation quantum system , Will be in 2023-2024 It was launched and expanded to 7000 Qubit per qubit , And this time The experimental prototype machines and tools have 500 Multiple qubits , And based on Zephyr Topology technology realizes 20 Fully connected qubits .

D-Wave Director of quantum annealing products Emile Hoskinson Express ： “ to open up Advantage2 Use of prototypes , Designed to share with users D-Wave What you are learning and getting feedback from the user community , To continue building the complete Advantage2 System .”

Hoskinson Further sermon ：“Advantage2 yes D-Wave A newly designed quantum computer , future , With Advantage2 Put into use ,D-Wave Connectivity and low noise will prove to be a delivery tool for higher performance . Provide Advantage2 Commercial access to prototypes , Let us have the opportunity to bring new quantum application experience to our customers , To see the future .”

before ,D-Wave A new low noise 、 Multilayer superconducting integrated circuit manufacturing process , It improves performance 、 It has a significant effect on improving the coherence of quantum bits .

Hoskinson say ：“ By utilizing our extensive experience in the development and manufacturing of superconducting circuit architectures ,D-Wave It has higher scalability .D-Wave Our ultimate goal is to provide customers with complete solutions including gate model and quantum annealing , The quantum annealing system is a part of it .”

Hoskinson speak of ,Advantage2 QPU And its prototype shows higher quantum bit connectivity ,Zephyr Topology technology will replace what has been used in Advantage QPU Upper Pegasus Topology Technology , Quantum chips with shorter input chains , So as to bring higher quality solutions .

stay D-Wave released Advantage2 In the prototype technical report ,Advantage2 The prototype is superior to in four aspects Advantage QPU The ability of ：

More tightly embedded . stay Advantage QPU Based on Zephyr The input chain ratio embedded in the structure is Advantage QPU Based on Pegasus The embedded chain is short 6% To 21%. Use two embedded in Advantage2 Prototypes and Advantage( Performance updates )QPU A comparison of the input types of , The average chain length is increased 25%.

Better solution for embedded input . In the use of two types of tests that meet the input conditions ,Advantage2 The solution quality of the prototype solver , At Gotha 82% Is better than Advantage solver .

A better solution for native input . The primary input is used to isolate the contribution of the increased energy scale （ And Zephyr Resulting in different embedding quality ）. For three of the four input categories ,Advantage2 The prototype solver is in 77%、87% and 89% Found a better solution in the case of . Both solvers are effectively bound to the fourth class , And always return to the best or second best solution .

As the energy scale increases , It reduces the error rate . The quantum coupler and short chain were tested at the component level for three times . These tests show that , And Advantage QPU comparison ,Advantage2 The prototype has been improved by 94%、103% and 72%.
