Quantum computing topological invariants of two-dimensional quantum matter
Quantum algorithms provide a potential strategy for solving computational problems that are intractable by classical means. Computing the topological invariants of topological matter is one central problem in research on quantum materials, and a variety ...

Quantum Computing Tutorial Bits vs Qubits and Shors Algorithm [PDF]
, 2017 The speculative inquiry that computation could be done in general more efficiently by utilizing quantum effects was introduced by Richard Feynman Peter Shor described a polynomial time quantum algorithm for factoring integers by a quantum machine which

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots
Advanced Functional Materials, EarlyView.CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Quantum-coherent mixtures of causal relations
Nature Communications, 2017 The set of causal relations that can connect two systems is much richer in the quantum world. Here the authors show that it is possible to have a coherent mixture of a cause-effect and a common-cause mechanism between two systems, realizing this in a ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, EarlyView.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Advanced Functional Materials, EarlyView.Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Quantum Gravity on a Quantum Computer? [PDF]
Foundations of Physics, 2013 EPR-type measurements on spatially separated entangled spin qubits allow one, in principle, to detect curvature. Also the entanglement of the vacuum state is affected by curvature. Here, we ask if the curvature of spacetime can be expressed entirely in terms of the spatial entanglement structure of the vacuum.
