The Quantum Echoes Algorithm
Quantum Echoes is an innovative algorithm inspired by sonar technology. It works by running a series of operations on an entangled 105-qubit array, perturbing a single qubit, and then reversing the operations. This process creates a 'butterfly effect' that reveals information about the quantum system
