The quantity theory of money (often abbreviated QTM) is a hypothesis within monetary economics which states that the general price level of goods and services is directly proportional to the amount of money in circulation (i.e., the money supply), and that the causality runs from money to prices. This implies that the theory potentially ...
Wiesner's quantum money scheme was first published in 1983. [1] A formal proof of security, using techniques from semidefinite programming, was given in 2013. [2]In addition to a unique serial number on each bank note (these notes are actually more like cheques, since a verification step with the bank is required for each transaction), there is a series of isolated two-state quantum systems.

Quantum finance is an interdisciplinary research field, applying theories and methods developed by quantum physicists and economists in order to solve problems in finance. It is a branch of econophysics. Quantum computing is now being used for a number of financial applications, including fraud detection, stock price prediction, portfolio ...
Monetary economics is the branch of economics that studies the different theories of money: it provides a framework for analyzing money and considers its functions ( as medium of exchange, store of value, and unit of account), and it considers how money can gain acceptance purely because of its convenience as a public good.

The alternative to a commodity money system is fiat money which is defined by a central bank and government law as legal tender even if it has no intrinsic value. Originally fiat money was paper currency or base metal coinage, but in modern economies it mainly exists as data such as bank balances and records of credit or debit card purchases, [3] and the fraction that exists as notes and coins ...
4 key differences between money market accounts and funds. While both options offer ways to earn interest on your cash, there are several important differences that define how they work and how ...
The word quantum comes from the Latin word for "how much" (as does quantity). Something that is quantized, as the energy of Planck's harmonic oscillators, can only take specific values. For example, in most countries, money is effectively quantized, with the quantum of money being the lowest-value coin in circulation. Mechanics is the branch of ...
