A desktop computer for educaton & research Shenzhen SpinQ Technology - Desktop Quantum Computer at around ~$5k for 2 qubits - Cost of a commercial quantum computer ~$ 10 million for 50 qubits - Compound at the heart is dimethylphosphite - Tetrahedral molecule consisting of one phosphorous atom, one hydrogen atom, an oxygen and two CH3O groups - Dimethylphosphite is ideal because the phosphorous and hydrogen atoms are bonded to each other and close enough to interact while also capable of being manipulated independently. - uses permanent magnets to create a highly powerful, regular magnetic field - employs a technique called shimming that generates another magnetic field capable of cancelling out any irregularities in the stronger field. -One of the drawbacks of quantum computation based on nuclear magnetic resonance is that the machines cannot handle more than a dozen or so qubits. ------- #quantum links: - https://arxiv.org/abs/2101.10017 - https://www.discovermagazine.com/technology/a-desktop-quantum-computer-for-just-usd5-000 - https://spinq.com.cn/
