Quantum 6, 770 (2022). https://doi.org/10.22331/q-2022-07-20-770 We introduce a quantum algorithm to compute the market risk of financial derivatives. Previous work has shown that quantum amplitude estimation can accelerate derivative pricing quadratically in the target error […]
Quantum 6, 769 (2022). https://doi.org/10.22331/q-2022-07-20-769 We present an algorithm to reliably generate various quantum states critical to quantum error correction and universal continuous-variable (CV) quantum computing, such as Schrödinger cat states and Gottesman-Kitaev-Preskill (GKP) grid […]
Quantum 6, 768 (2022). https://doi.org/10.22331/q-2022-07-20-768 Quantum Phase Estimation is one of the most useful quantum computing algorithms for quantum chemistry and as such, significant effort has been devoted to designing efficient implementations. In this article, […]
Quantum 6, 767 (2022). https://doi.org/10.22331/q-2022-07-20-767 Quantum error correction has recently been shown to benefit greatly from specific physical encodings of the code qubits. In particular, several researchers have considered the individual code qubits being encoded […]
Quantum 6, 766 (2022). https://doi.org/10.22331/q-2022-07-14-766 We study a three-fold variant of the hypergraph product code construction, differing from the standard homological product of three classical codes. When instantiated with 3 classical LDPC codes, this “XYZ […]
Quantum 6, 765 (2022). https://doi.org/10.22331/q-2022-07-14-765 It is well-known that in a Bell experiment, the observed correlation between measurement outcomes – as predicted by quantum theory – can be stronger than that allowed by local causality, […]
Quantum 6, 764 (2022). https://doi.org/10.22331/q-2022-07-14-764 Measuring time means counting the occurrence of periodic phenomena. Over the past centuries a major effort was put to make stable and precise oscillators to be used as clock regulators. […]
Quantum 6, 763 (2022). https://doi.org/10.22331/q-2022-07-14-763 In general, for a bipartite quantum system $mathbb{C}^{d}otimesmathbb{C}^{d}$ and an integer $k$ such that $4leq kle d$,there are few necessary and sufficient conditions for local discrimination of sets of $k$ […]
Quantum 6, 762 (2022). https://doi.org/10.22331/q-2022-07-14-762 We consider a quasi-probability distribution of work for an isolated quantum system coupled to the energy-storage device given by the ideal weight. Specifically, we analyze a trade-off between changes in […]
Quantum 6, 761 (2022). https://doi.org/10.22331/q-2022-07-11-761 Significant effort in applied quantum computing has been devoted to the problem of ground state energy estimation for molecules and materials. Yet, for many applications of practical value, additional properties […]
