The first quantum computers that are put on sale for all users are a reality. They are the Gemini Mini, Gemini and Triangulum, developed by the Chinese company SpinQ TechnologyThey can already be bought in Japan. Pricing for the most basic model, the two-cubit 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 a similar device with the models you have announced.

How are these quantum computers?

The key is the dimethylphosphite. This is a tetrahedral molecule composed of a phosphorus (P) atom, a hydrogen (H) atom, oxygen and two CH3O groups, it is used as a working substance 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 substance for small quantum computers: in it, the phosphorus and hydrogen atoms act as separate qubits, interconnected and close enough to one another to achieve effective interaction and manifest quantum properties. But at the same time, can be controlled independently.

In the company’s devices, several drops of dimethylphosphite are placed in a small, sealed vial, around which are placed magnets that create a magnetic field of up to one tesla. There is also a second ring of security.

The models that are for sale

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. The coherence retention time is >20 ms. The device weighs 14 kilograms with dimensions of 200 × 350 × 260mm and is priced at around $8,700. The device has built-in CASTOR software, which allows you to simulate the operation of eight qubits.

The model gemini it 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 contains two qubits, but it can simulate eight. The qubit frequency (H) is 41.3 ± 2 MHz. The coherence retention time is >20 ms. The device weighs 44 kilograms with dimensions of 600 × 280 × 530 mm.

The last one is called triangle and, unlike the previous two, it is a three-qubit system with a qubit frequency (F) of 39.6 ± 1 MHz. The coherence retention time is >40 ms. It has built-in program software, SpinQuasar, which probably also gives it the ability to simulate more. The device weighs 40 kilograms with dimensions of 610 × 330 × 550 mm.
