SpinQ Introduces Trio of Portable Quantum Computers
Just announced by Switch-Science Three quantum computing products The company claims to be the world’s first portable quantum computer. A new quantum computing product supplied by SpinQ Technology, a Chinese quantum computing company based in Shenzhen, is designed for educational purposes. Its purpose is to democratize access to physical quantum computing solutions that can be deployed (and redeployed) at will. But given the actual quantum machines on offer, none of these (internally we call them “quantops”) are unlikely to be part of the quantum future.
New products, being developed with education in mind, show the highest number of qubits at 3 (compare Google’s Sycamore or IBM’s 433-qubit Osprey Quantum Processing Unit). [QPU], both based on superconducting qubits). This is not enough to run viable problem-solving quantum computing inside these machines, but it is enough for users to program and run quantum circuits – integrated, educational , or a single custom algorithm.
The new “Quantops” – Gemini Mini, Gemini, Triangulum – differ in complexity and design. But they all have fully integrated quantum computing systems that can operate at room temperature. Its power depends on the very nature of the qubit. SpinQ utilizes nuclear magnetic resonance (NMR) spin qubits, a technology first introduced in 1997. And that’s their main problem. very limited scaling capabilities, and its quantum capabilities are … relatively questionable. All NMR-related studies in the past few years have failed to demonstrate the entanglement function of these particular qubits. This is one of the most important quirks of the quantum world and one of the factors that lead to extreme performance potential (for certain specialized tasks).
The Gemini Mini is the company’s entry-level product, a 200 x 350 x 260mm, 14 kg system with a two-qubit solution (hence the name) with a coherence time of over 20 ms. According to the company, the Gemini Mini can perform over 30 gate operations with a single qubit, and over 10 gate operations using a two-qubit circuit. It features an integrated screen and supports 18 demo algorithms with documentation and training material. Gemini is available for ~1,118,000 Yen (~$8,104). Power consumption is 60 W (including the power required for the integrated screen).
The Gemini sheds the screen integrated with the ‘Mini’ but doesn’t increase the qubit count. Instead, the increased complexity of the system allows more complex gate operations to be performed. Up to 200 gate depths with one-qubit operations and more than 20 gates with two-qubit operations are possible while maintaining the quoted “>20 ms” coherence time. A more complex product and containing only 6 demo algorithms, SpinQ seems to target this product towards more advanced quantum computing users. Pricing is also more “advanced”, at 5.72 million yen (~$41,510), about five times as much. With a volume of 600 x 280 x 530 mm in an Alienware-like enclosure, power consumption (without an integrated screen) is up to 100 W and weight is ~44 kg (portability seems to be relative) .
The third product, Triangulum, is the most advanced, bigger, worse, and much more expensive (around $57,400). Triangulum provides three NMR spin qubits with coherence times greater than 40 ms (he doubles the power of the Gemini pair) in a 40 Kg, 610 x 330 x 560 mm chassis. SpinQ seems to have designed Triangulum for higher coherence times. This means that the spin qubit state can decoheal and do more work before all the work is lost. But quantum (and especially NMR devices) has something to give. The depth of gate operations per quantum circuit is reduced compared to Gemini, offering only 40 gate-depth operations in a single qubit and up to 8 gate-depth operations. 2 or 3 qubit operations. This seems like a necessary evil due to the addition of qubits and the increase in coherence time. The added noise had to be compensated for due to the apparent inferiority of NMR scaling capabilities. The Triangulum’s power consumption rating of 330W may also not help with system consistency.
SpinQ’s computer is not the quantum future. The technology they’re based on is unlikely to become one of the “successful” designs to open the door to post-NISQ (Noisy Intermediate-Scale Quantum) quantum computing. Given that multiple companies (such as IBM, Nvidia, AWS, and SpinQ itself) already offer cloud-based quantum computer simulators, it’s a good idea for the company to develop, manufacture, and deliver these systems. It is interesting that you chose These will allow users to choose from different types of qubits, and will also greatly enhance quantum computing capabilities. All things considered, this product is unlikely to ignite the world of quantum computing. may help raise interest in
