Efficient Linear Optics Quantum Computation: Supplementary Information
In the paper we claimed that teleportation with |tn〉 satisfies that if 0 < k < n + 1, then the teleported state appears in mode n + k and only needs to be corrected by applying a phase shift. The modes 2n − l are in state 1 for 0 ≤ l < (n − k) and can be reused in future preparations requiring single photons. The modes 2n − l are in state 0 for n − k < l < n. If k = 0 we learn that the input st...
متن کاملQuantum Computation with Linear Optics
We present a constructive method to translate small quantum circuits into their optical analogues, using linear components of present-day quantum optics technology only. These optical circuits perform precisely the computation that the quantum circuits are designed for, and can thus be used to test the performance of quantum algorithms. The method relies on the representation of several quantum...
متن کاملErasure Thresholds for Efficient Linear Optics Quantum Computation
Using an error models motivated by the Knill, Laflamme, Milburn proposal for efficient linear optics quantum computing [Nature 409,46–52, 2001], error rate thresholds for erasure errors caused by imperfect photon detectors using a 7 qubit code are derived and verified through simulation. A novel method – based on a Markov chain description of the erasure correction procedure – is developed and ...
متن کاملExperimental nonlinear sign shift for linear optics quantum computation.
We have realized the nonlinear sign shift operation for photonic qubits. This operation shifts the phase of two photons reflected by a beam splitter using an extra single photon and measurement. We show that the conditional phase shift is (1.05+/-0.06)pi in clear agreement with theory. Our results show that, by using an ancilla photon and conditional detection, nonlinear optical effects can be ...
متن کاملExploring a New Post-Selection Condition for Efficient Linear Optics Quantum Computation
Recently, it was shown that fundamental gates for theoretically efficient quantum information processing can be realized by using single photon sources, linear optics and quantum counters. One of these fundamental gates is the NS-gate, that is, the one-mode non-linear sign shift. In this work, firstly, we prove by a new rigorous proof that the upper bound of success probability of NS-gates with...
