• Authors: Hazel Murray, Jerry Horgan, Joao F. Santos, David Malone, Harun Siljak
• Abstract summary: We describe a digital cash scheme created by Dmitry Gavinsky, which utilise the capability of quantum computing. For both the creation and verification of quantum coins we convert the algebraic steps into computing steps. As part of this, we describe the methods used to convert information stored on classical bits to information stored on quantum bits.

• Abstract: Quantum computing has the power to break current cryptographic systems, disrupting online banking, shopping, data storage and communications. Quantum computing also has the power to support stronger more resistant technologies. In this paper, we describe a digital cash scheme created by Dmitry Gavinsky, which utilises the capability of quantum computing. We contribute by setting out the methods for implementing this scheme. For both the creation and verification of quantum coins we convert the algebraic steps into computing steps. As part of this, we describe the methods used to convert information stored on classical bits to information stored on quantum bits.

  In the 1970s, Wiesner introduced the concept of quantum money, where quantum states generated according to specific rules function as currency. Quantum computers capable of minting and preserving quantum money have not yet emerged. Existing quantum channels are not stable enough to support the efficient transmission of quantum states for quantum money.

  We review several ideas indicating how multilevel quantum systems, also known as qudits, can be used for efficient realization of quantum algorithms. We focus on techniques of leveraging qudits for simplifying decomposition of multiqubit gates, and for compressing quantum information by encoding multiple qubits in a single qudit. These theoretical schemes can be implemented with quantum computing platforms of various nature, such as trapped ions, neutral atoms, superconducting junctions, and quantum light.
