Editing Quantum Cheque (section)

==Properties==

* In the signing process, the quantum one-way function used to create the cheque for the account holder is assumed to take polynomial time to compute and is hard to invert.
* In the verification process, the bank sets a thresholding security parameter <math>\kappa</math>. The swap test is passed if <math>\{ \langle\psi^{(i)}|\psi^{,(i)}\rangle \geq \kappa\}_{i=1:l}</math>
* No quantum memory would be required for the account holder to store the quantum check if the transaction is occurring in real-time.
* This protocol can be realized, efficiently, with few qubit systems, without compromising on the security
* Security: This protocol is impossible to counterfeit and non-repudiation by signatory is impossible here.
