What is qsmp?

QSMP, also known as Quantum Secure Multi-party Computation, is a cryptographic protocol that allows multiple parties to jointly compute a function over their private inputs without revealing those inputs to each other.

In QSMP, each party holds their own private input and shares it with the other parties in an encrypted form. The parties then collectively compute the function using their encrypted inputs, without ever decrypting them or revealing them to the other parties. This ensures the privacy and security of each party's input while still allowing them to jointly compute the desired function.

QSMP is typically used in scenarios where multiple parties need to jointly compute a function over their private data, such as in collaborative data analysis, secure voting systems, or secure financial transactions. It provides a way for parties to share and compute data while maintaining privacy and confidentiality.
