Blueprint for a Scalable Photonic Fault-Tolerant Quantum Computer
J. Eli Bourassa, Rafael N. Alexander, Michael Vasmer +10
Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature. However, no concrete architecture has been presented so far…
Progress towards practical qubit computation using approximate Gottesman-Kitaev-Preskill codes
Ilan Tzitrin, J. Eli Bourassa, Nicolas C. Menicucci +1
Encoding a qubit in the continuous degrees of freedom of an oscillator is a promising path to error-corrected quantum computation. One advantageous way to achieve this is through G…
Operational symmetries of entangled states
Ilan Tzitrin, Aaron Z. Goldberg, Jesse C. Cresswell
Quantum entanglement obscures the notion of local operations; there exist quantum states for which all local actions on one subsystem can be equivalently realized by actions on ano…
Perturbative expansion of entanglement negativity using patterned matrix calculus
Jesse C. Cresswell, Ilan Tzitrin, Aaron Z. Goldberg
Negativity is an entanglement monotone frequently used to quantify entanglement in bipartite states. Because negativity is a non-analytic function of a density matrix, existing met…
On the local equivalence of complete bipartite and repeater graph states
Ilan Tzitrin
Classifying locally equivalent graph states, and stabilizer states more broadly, is a significant problem in the theories of quantum information and multipartite entanglement. A sp…
