Fusion gates are common operations in photonic quantum information platforms, where they are employed to create entanglement. Here, the authors propose a quantum computation scheme where the same measurements used to generate entanglement can also be

Parity-time-symmetric (PT-symmetric) Hamiltonians are generally non-Hermitian and give rise to exotic behavior in quantum systems at exceptional points, where eigenvectors coalesce. The recent realization of PT-symmetric Hamiltonians in quantum syste

We introduce fusion-based quantum computing (FBQC) - a model of universal quantum computation in which entangling measurements, called fusions, are performed on the qubits of small constant-sized entangled resource states. We introduce a stabilizer f

Advances in control techniques for vibrational quantum states in moleculespresent new challenges for modelling such systems, which could be amenableto quantum simulation methods. Here, by exploiting a natural mappingbetween vibrations in molecules an

We demonstrate quantum logic using narrow linewidth photons that are produced with an a-priory non-probabilistic scheme from a single 87Rb atom strongly coupled to a high- nesse cavity. We use a controlled-NOT gate integrated into a photonic chip to

A new model for trading equities in a multiple market environment is presented and discussed. Instead of allowing continuous trading, the model proposes using a series of calls that occur in rapid succession. The calls are coordinated across venues s

Fear of adverse selection has been cited by buy-side traders as one of the reasons for the decline in block market share, and concerns of adverse selection from executing in dark pools and with high frequency trading firm contras have also been raise

This article presents a framework for quantifying the value of liquidity. The authors suggest that liquidity is valuable from both cost and risk perspectives. The value of liquidity from a cost perspective may be quantified by using a cost model to c

The volatility that gripped the market during the latter half of 2008 led many traders to change their trading behavior. The relative volume of block trades that were executed in the market decreased during this period. Many traders moved away from t
