That these codes allow indeed for quantum computations of arbitrary length is the content of the quantum threshold theorem, found by Michael Ben-Or and Dorit Aharonov, which asserts that you can correct for all errors if you concatenate quantum codes such as the CSS codes—i.e. re-encode each logical qubit by the same code again, and so on, on ...
Quantum Break is a 2016 action-adventure third-person shooter video game developed by Remedy Entertainment and published by Microsoft Studios for Windows and Xbox One.The game centers on Jack Joyce (Shawn Ashmore), granted time manipulation powers after a failed time-machine experiment, as he comes into conflict with former friend Paul Serene over how to deal with an apocalyptic "End of Time".
Once the logical qubit is encoded, errors on the physical qubits can be detected via stabilizer measurements. A lookup table that maps the results of the stabilizer measurements to the types and locations of the errors gives the control system of the quantum computer enough information to correct errors. [4]
Quantum error-correcting codes restore a noisy, decohered quantum state to a pure quantum state. A stabilizer quantum error-correcting code appends ancilla qubits to qubits that we want to protect. A unitary encoding circuit rotates the global state into a subspace of a larger Hilbert space.
Gil Kalai. "Perpetual Motion of The 21st Century?". Scott Aaronson. "PHYS771 Lecture 14: Skepticism of Quantum Computing": «The entire content of the Threshold Theorem is that you're correcting errors faster than they're created.

The classical analog of the CNOT gate is a reversible XOR gate. How the CNOT gate can be used (with Hadamard gates) in a computation.. In computer science, the controlled NOT gate (also C-NOT or CNOT), controlled-X gate, controlled-bit-flip gate, Feynman gate or controlled Pauli-X is a quantum logic gate that is an essential component in the construction of a gate-based quantum computer.
Players control Jacob Thomas, a firefighter, as he attempts to deal with various issues at research facilities in outer space. Players must contend with both terrorists and monsters while attempting to rescue survivors using firefighting equipment.
