Precision For A Qubit Operation and Failure of Achieving Quantum Supremacy
Abstract
M. Dyakonov [IEEE Spectrum, 2019] asked: what precision is required for manipulating a quantum gate, and what role is the notion of ENERGY playing in quantum computing theory. We answer the questions by investigating the Quantum Fourier Transformation (QFT). We show that the precision for a qubit operation is no less than $4.72694\times 10^{-36}$, in accordance with the energy of a free particle. Quantum entanglement is indispensable to quantum supremacy. The present quantum computers have failed to instantiate quantum entanglement up to our expectation, due to inexact qubit operations. Quantum transition incurred during the transition of space-time continuum covertly changes qubits and corrupts quantum supremacy.
