Abstract
In some embodiments, a computing system may comprise a memory for storing a ledger; a computer processor for verification of the ledger, wherein the computer processor comprises at least one of a classical computer processor configured to run a virtual quantum machine and a quantum computer comprising a plurality of qubits; wherein the ledger is configured to store arbitrary classical information and quantum information which is verifiable using the computer processor. Furthermore, in some embodiments the computing system is configured to perform operations comprising: adding to the ledger using the computer processor to solve a mathematically difficult problem which is Quantum-Merlin-Arthur-complete (QMA-complete). In embodiments, a blockchain includes a quantum state. In some aspects, a unitary operator corresponding to a quantum rotation is found when new transaction data are to be secured in the blockchain.
