Experimental Method for Manipulation of the State of Multi-Phi-Bit Systems
This invention is a method to experimentally navigate the Hilbert space of two logical phi-bits. A “phi-bit,” is a two-state degree of freedom of an acoustic wave (an acoustic spin), which can be in a coherent superposition of states with complex amplitude coefficients. Phi-bits are therefore analogues of qubits. The inventors have developed...

A Method for the Practical Implementation of Scalable Quantum-Like Gates using Logical Phi-Bits
This technology is a breakthrough in the development of acoustic-based (phi-bit based) quantum-analogue computing platform by enabling the design of scalable unitary operations (gates) that do not need to be decomposed into circuits of elementary gates. This should lead to quantum-like information processing approaches that are more effective than those...
