There are two fundamental types of errors on qubits: X and Z.They describe what is known as the threshold theorem, which claims that. The authors introduce the stabilizer approach and describe additional QEC codes. This description allows codes to be analyzed and developed in a more formal and systematic way. The central problem is the question The central problem is the question of how to physically implement the surface code in viable physical qubit systems. Many QEC codes can be conveniently and compactly described through the use of stabilizers. There are other methods to reduce decoherence, but it is believed that QEC will be present in any QC. According to quantum information theorist Scott Aaronson: 'The entire content of the Threshold Theorem is that you're correcting errors faster than they're. Measuring individual qubits to determine whether an error has occurred will destroy the superposition necessary to maintain a logical state, so measurements which detect errors must be done indirectly, using ancilla qubits. quantum error-correcting codes (such as the Steane code). Quantum Error Correction: the best hope for success. Then, one can use these better gates to recursively create even better gates, until one has gates with the desired failure probability, which can be used for the desired quantum circuit.More redundancy in the encoding scheme tends to lead to better protection against errors. A variety of encoding schemes exist to protect qubits against external noise, and the effects of imprecise control.Large-scale computations require much lower logical error rates than those we can produce directly in hardware. Quantum Errors There are three big challenges to QEC: 1.No-Cloning Theorem: There is no operator U c that can perform the following mapping: U c( ) ( ) 2.Continuous errors 3.Measurement collapses state information. Holographic codes can admit erasure thresholds comparable to that of the widely-studied surface code, and likewise for their threshold against Pauli errors.
