We should strive to achieve it, as that's when Quantum Computing becomes applicable?

Decoherence - Quantum Information leaks, destabilizing the superposition. 
A lot of physical qubits are needed to create a logical qubit.]]> 2020-04-20 12:22:56 UTC https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517315826 https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517317269 Quantum Supremacy refers to the state where a quantum can solve a problem in a much faster time frame than a traditional computer.

Lack of logical qubits - need a high amount of physical qubits and need to improve coherence times.
Error handling - Quantum computing is very error prone and error detection is tough as states of qubits cannot be measured.

Because of decoherence, it is only possible to maintain the qubit for a few microseconds. Because of noise, a lot of computation power is needed.]]> 2020-04-20 12:25:01 UTC https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517320394 https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517321154 Quantum Supremacy is a milestone for a quantum computer being able to solve a problem a lot faster than a regular computer. 
We should try to achieve it within the means possible. ]]> 2020-04-20 12:25:25 UTC https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517321154 https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517322395 Quantum supremacy refers to when quantum computers can solve (particular) problems faster than classical computers. Faster is a bit vague, but often we mean that quantum supremacy is achieved when the quantum algorithm has a lower computational complexity than the classical algorithm.

The sum qubit state can only exist for a very short period of time, so whatever computation is taking place is limited by this.

This requires designing a specific problem that theoretically performs better on a quantum computer.]]> 2020-04-20 12:27:39 UTC https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517325922 https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517329576 They're "noisy" and interact with their enviroments. We need a lot of physical qubits to simulate a single physical qubit. 
To reduce noise is an entire field in itself.]]> 2020-04-20 12:29:17 UTC https://padlet.com/ahwerner/6aif5b4gcekbqt16/wish/517329576
