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.

Qubits are anything that can be in one of two states, or both at the same time. This occurs in nature, with particles, and can also be engineered with special circuits.
At Nvidia GTC,
