IBM has established a landmark (10 November, 2017) in quantum computing by announcing quantum computer with 50 qubits. The company has made available on cloud five and sixteen qubit machines to everybody absolutely FREE! On IBM Real Chip Quantum Computers the quantum state is preserved for about 90 microseconds—a record for the industry, but still this is extremely short period of time. Problems requiring lesser time to solve then become important in this situation.
Recently, I published a new exponentially fast quantum algorithm for searching targets in the unstructured database. I report here about the SUCCESSFUL EXPERIMENTS I performed on IBM Real Chip Quantum Computer and IBM Simulator using my recently published new search algorithm:

As an example, I have attached the image of a quantum circuit and corresponding histogram for the experiment done on IBM Real Chip Computer to search target = 4, among 2^5 = 32 numbers in a single iteration! Also, I have attached the quantum circuit and corresponding histogram depicting correctly obtained answer tested on IBM Simulator to search the target = 9,54,955 (= 11101001001001001011, in binary notation), among 2^20 = 10,48,576 numbers, also, again in one shot!! Both IBM Real Chip Computer and Simulator worked EXCELLENTLY!!!
I used the “composer” provided by IBM and constructed quantum circuits. I formed these circuits using the buttons and tools provided by IBM for the users and tested these circuits successfully on IBM Real Chip Quantum Computers as well as on IBM Simulator.

IBM now have a 50 qubit computer! This is great and praiseworthy achievement by IBM! They can now search a desired target in the unstructured database made up of 2^50 items in a single shot!! Nobody has yet solved such huge problems using quantum computers. IBM people can now verify the real power of a quantum computer by searching out the desired target in this phenomenally huge unstructured database containing
2^50 = 1,125,899,906,842,624 items in a single shot!!!
