Abstract:
Unlike classical money, which is hard to forge for practical reasons (e.g. producing paper with a certain property), quantum money is attractive because its security might be based on the no-cloning theorem. The first quantum money scheme was introduced by Wiesner circa 1970. Although more sophisticated quantum money schemes were proposed, Wiesner’s scheme remained appealing because it is both conceptually clean as well as relatively easy to implement. We show efficient adaptive attacks on Wiesner’s quantum money scheme [1] (and its variant by Bennett et al. [2]), when valid money is accepted and passed on, while invalid money is destroyed. We propose two attacks, the first is inspired by the Elitzur-Vaidman bomb testing problem [3, 4], while the second is based on the idea of protective measurements [5]. It allows us to break Wiesner’s scheme with 4 possible states per qubit, and generalizations which use more than 4 states per qubit. The attack shows that Wiesner’s scheme can only be safe if the bank replaces valid notes after validation.

Abstract:
Money objects, from coins to bitcoins, are used in economic exchange as a way of putting a number on the fuzzy concept of worth or value. They are inherently dualistic in that they combine the properties of abstract numbers with the properties of owned objects. As a result of this duality at its core, the money system exhibits the properties of a macroscopic quantum system, including entanglement, indeterminacy and interference, with money objects playing a special role as a measurement device. This article argues that, by virtue of its dualistic nature, money acts as a vector of transmission that scales up the properties of quantum mind to the global level. By bringing money back into the picture and providing an alternative to the mechanistic vision of mainstream economics, quantum social science promises to change the way we see and treat the economy, with implications for international relations and security.

Abstract:
We put forward the idea that classical blockchains and smart contracts are potentially useful primitives not only for classical cryptography, but for quantum cryptography as well. Abstractly, a smart contract is a functionality that allows parties to deposit funds, and release them upon fulfillment of algorithmically checkable conditions, and can thus be employed as a formal tool to enforce monetary incentives. In this work, we give the first example of the use of smart contracts in a quantum setting. We describe a simple hybrid classical-quantum payment system whose main ingredients are a classical blockchain capable of handling stateful smart contracts, and quantum lightning, a strengthening of public-key quantum money introduced by Zhandry [55]. Our hybrid payment system employs quantum states as banknotes and a classical blockchain to settle disputes and to keep track of the valid serial numbers. It has several desirable properties: it is decentralized, requiring no trust in any single entity; payments are as quick as quantum communication, regardless of the total number of users; when a quantum banknote is damaged or lost, the rightful owner can recover the lost value.

Abstract:
We discuss the possibility of creating money that is physically impossible to counterfeit. Of course, "physically impossible" is dependent on the theory that is a faithful description of nature. Currently there are several proposals for quantum money which have their security based on the validity of quantum mechanics. In this work, we examine Wiesner's money scheme in the framework of generalised probabilistic theories. This framework is broad enough to allow for essentially any potential theory of nature, provided that it admits an operational description. We prove that under a quantifiable version of the no-cloning theorem, one can create physical money which has an exponentially small chance of being counterfeited. Our proof relies on cone programming, a natural generalisation of semidefinite programming. Moreover, we discuss some of the difficulties that arise when considering non-quantum theories.

Abstract:
In the year 2002, Y. V Reddy introduced a new thought in monetary economics theory, especially about transmission mechanism of monetary policy. Reddy classified the channeIs of transmission mechanism into three types, there are quantum channel, interest rate channel, and asset price channel. Quantum channel consists of two channels, there are money channel and credit channel. This research will examine the differences between money channel and credit channeI, the factors which affect volume of money supply (M2) and credit, the stability of quantum channel, and also effectiveness of quantum channel, especially related on its role to push the economic growth. This research uses a monthly data from the year 1993 until 2005. The analysis of this research divided into three parts of period, pre-crisis period (1993-1996), crisis period (19972OO1), and post-crisis period (2002-2005). In the precrisis period, credit channel more stable in transmission mechanism of monetary policy and more effective to push the economic growth. In the crisis, quantum channel did not effective to push economic growth. In the post-crisis period quantum channel also did not effective to push the economic growth.
