Four different quantum systems with four different types of qubits were on display at Nvidia GTC, here's how they all work. Infleqtion’s neutral atom quantum computer system uses lasers to cool Cesium atoms down to near absolute zero. This year, I visited the quantum corner at Nvidia GTC, determined to wrap my mind around what has so far been a pretty intimidating topic to me: quantum computers. This technology promises to revolutionize industries such as finance, cybersecurity, chemistry and more. To get there, however, it needs to crack some very hard problems. One question still swirling in the quantum computing world is what exactly should qubits be made from. Classical computer bits are anything that exists in a binary state (either a 0 or a 1, a true or a false). These are often physically represented as an electrical charge that’s either on or off.
