Research on quantum technology spans multiple disciplines: physics, computer science, engineering, and mathematics. The objective of this manuscript is to provide an accessible introduction to this emerging field for economists that is centered around quantum computing and quantum money. We proceed in three steps. First, we discuss basic concepts in quantum computing and quantum communication, assuming knowledge of linear algebra and statistics, but not of computer science or physics. This… 
Application of Quantum Computers in Foreign Exchange Reserves Management
It is proven that in principle it will be possible to apply quantum computers in FX reserves management in the future and serves as an introduction to quantum computing for the central banks and financial market supervisory authorities.
Revisiting the Properties of Money
This paper makes the first exhaustive attempt to identify and define the properties of all physical and digital forms of money in an expanded version of the original functions-andproperties framework of money that includes societal and regulatory objectives.


Quantum Computing: A Gentle Introduction
A thorough exposition of quantum computing and the underlying concepts of quantum physics, explaining all the relevant mathematics and offering numerous examples, makes quantum computing accessible to students and professionals in mathematics, computer science, and engineering.
Digitized adiabatic quantum computing with a superconducting circuit.
The demonstration of digitized adiabatic quantum computing in the solid state opens a path to synthesizing long-range correlations and solving complex computational problems.
Quantum computing and the entanglement frontier
This study is motivated by the observation (widely believed but unproven) that classical systems cannot simulate highly entangled quantum systems efficiently, and it hopes to hasten the day when well controlled quantum systems can perform tasks surpassing what can be done in the classical world.
Complexity-Theoretic Foundations of Quantum Supremacy Experiments
General theoretical foundations are laid for how to use special-purpose quantum computers with 40--50 high-quality qubits to demonstrate "quantum supremacy": that is, a clear quantum speedup for some task, motivated by the goal of overturning the Extended Church-Turing Thesis as confidently as possible.
Nobel Lecture: Superposition, entanglement, and raising Schrödinger's cat
Experimental control of quantum systems has been pursued widely since the invention of quantum mechanics. In the first part of the 20th century, atomic physics helped provide a test bed for quantum
Toward the first quantum simulation with quantum speedup
It is argued that simulating the time evolution of spin systems is a classically hard problem of practical interest that is among the easiest to address with early quantum devices, and develops optimized implementations and performs detailed resource analyses for several leading quantum algorithms for this problem.
Quantum-state engineering with Josephson-junction devices
Quantum-state engineering, i.e., active control over the coherent dynamics of suitable quantum-mechanical systems, has become a fascinating prospect of modern physics. With concepts developed in
Demonstration of two-qubit algorithms with a superconducting quantum processor
A two-qubit superconducting processor and the implementation of the Grover search and Deutsch–Jozsa quantum algorithms are demonstrated and the generation of highly entangled states with concurrence up to 94 per cent is allowed.
Experimental quantum forgery of quantum optical money
This paper experimentally revisits the Wiesner idea of quantum money, and provides the security conditions for quantum money by investigating the physically-achievable limits on the fidelity of 1-to-2 copying of arbitrary sequences of qubits, and reports on the experimental quantum optical implementation of a quantum money protocol.
Breaking the 49-Qubit Barrier in the Simulation of Quantum Circuits
With the current rate of progress in quantum computing technologies, systems with more than 50 qubits will soon become reality. Computing ideal quantum state amplitudes for devices of such and larger
