The engineers at Purdue University and Tohoku University in Japan have built hardware to demonstrate the fundamental units.The computer is called the probabilistic computer “p Bits”, and it is capable of performing a calculation which is completely based on quantum theories.

The probabilistic computers also have large storage capacity with big bits storage capability. This quantum computer uses qubits, and they can be both zero and one at the same time. The researchers are now planning to introduce p-bits with large data storing capacity. “There is a useful subset of problems solvable with qubits that can also be solved with p-bits. You might say that a p-bit is a poor man's qubit,” stated SupriyoDatta, Professor of electrical and computer engineering, Purdue University.

The p-bits require room temperature to operate and it is one of the greatest advantages when compared to q-bits. The existing hardware can be adapted to build a probabilistic computer. The system also has a modified Magnetoresistive Random Access Memory (MRAM).

This system will help to introduce a device that serves as a basis for building probabilistic computers that have more efficiency to solve problems in areas such as encryption, cybersecurity, Artificial Intelligence, financial services, data analysis, and drug research. This system also plays a pivotal role in big data analysis and bioinformatics.
