The first quantum computer put on sale for all users is a reality. They are the Gemini Mini, Gemini and Triangulum, developed by Chinese company SpinQ Technology, and can be purchased in Japan. Pricing for the most basic model, the two-qubit Gemini Mini, starts at $8,700, while the most expensive model sits at $58,000.
According to the Japanese portal PC Watch, SpinQ Technology previously supplied its Quantum systems to educational institutions in China, Taiwan and Canada, where students could learn the principles of programming on these devices. Now anyone can buy similar equipment with the models you have announced.
How are these quantum computers?
The key is dimethylphosphate. It is a tetrahedral molecule composed of one phosphorus (P) atom, one hydrogen (H) atom, oxygen and two CH3O groups, it is used as a working material in SpinQ quantum systems. As a curiosity: At room temperature, this component appears as a colorless liquid.
Dimethylphosphite is considered by many experts to be an ideal material for tiny quantum computers: in it, phosphorus and hydrogen atoms act as separate qubits, interacting and binding together to achieve effective interactions and reveal quantum properties. are very close to each other. But, at the same time, they can be controlled independently.
In the company’s devices, several drops of dimethylphosphite are placed in a small, sealed vial, around which magnets are placed that create a magnetic field of up to one tesla. There is also a second layer of security.

Gemini Mini is a conditionally portable, entry-level two-qubit system (qubit frequencies 27 ± 1.5 MHz (H) and 11 ± 0.5 MHz (P)) equipped with a touch screen. Coherence retention time is > 20 ms. The device weighs 14 kg with dimensions of 200 × 350 × 260 mm and is priced around $8,700. The device has built-in CASTOR software, which allows you to simulate the operation of eight qubits.
The Gemini model is several times more expensive, around $43,000. It is not entirely clear what advantages it has over the Gemini Mini and why it is more expensive. Like the previous model, Gemini only has two qubits, but it can simulate eight. The qubit frequency (H) is 41.3 ± 2 MHz. Coherence retention time is > 20 ms. The device weighs 44 kg with dimensions of 600 × 280 × 530 mm.
The last one is called tri-qubit and, unlike the previous two, it is a three-qubit system with a qubit frequency (f) of 39.6 ± 1 MHz. Coherence retention time is >40 ms. It has built-in programming software, Spinquasar, which probably gives it even more simulation capabilities. The device weighs 40 kg with dimensions of 610 × 330 × 550 mm.
