A startup based in Shenzhen, China, called SpinQ has unveiled a quantum computer that can fit on a desk — and it costs less than $5,000, as Discover Magazine reports.
Are quantum computers expensive?
To increase stability, most experimental systems rely on heavy shielding and are cooled to operating temperatures approaching absolute zero. Thats makes quantum computers very expensive to build and maintain. Since they are so difficult and expensive to work with, you might ask: Why bother?
Can I buy a quantum computer?
They are reality. Google already claimed quantum supremacy in 2019 — their quantum computer solved a task in 200 seconds a classical computer would need 10,000 years for. So, even they do exist, unless you have a few million dollars you dont need, you wont be able to buy a quantum computer today.
How much does a 1 qubit quantum computer cost?
By most estimates, a single qubit costs around $10K and needs to be supported by a host of microwave controller electronics, coaxial cabling and other materials that require large controlled rooms in order to function. In hardware alone, a useful quantum computer costs tens of billions of dollars to build.
Do quantum computers exist yet?
Quantum computers were first proposed about 40 years ago, but they are only now becoming real machines. Making and controlling quantum computers has been elusive because their quantum weirdness arises from conditions that are hard to maintain.

Why are quantum computers so powerful?
Right now, the best quantum computers have about 50 qubits. Thats enough to make them incredibly powerful, because every qubit you add means an exponential increase in processing capacity. But they also have really high error rates, because of those problems with interference. Theyre powerful, but not reliable.

How much RAM does NASA use?
The system has 192 GB of memory per front-end and 7.6 petabytes (PB) of disk cache. Data stored on disk is regularly migrated to the tape archival storage systems at the facility to free up space for other user projects being run on the supercomputers.
Does the US government have a quantum computer?
The Department of Energys five quantum computing centers, housed at US national laboratories, are funded by a five year, $625 million project bolstered by $340 million worth of help from companies including IBM, Microsoft, Intel, Applied Materials and Lockheed Martin.
