The Quantum Matrix Processor, being announced today, is the world's first viable quantum array processor. Basic matrix operations are done instantaneously, with infinite procession. The programming environment is classic MATLAB.
I am pleased to be involved in today's announcement of the QMP, the Quantum Matrix Processor. This new device has been developed by Quantum Research Partners, a startup here in Santa Fe that was formed two years ago by a team from Los Alamos National Lab. I have been a consultant from the beginning of their project because they have based their design on classic MATLAB.
The QMP is similar conceptually to a GPU, or Graphics Processing Unit. It is a coprocessor that interfaces with the motherboard via an expansion slot such as PCI Express or Accelerated Graphics Port. Matrices are transferred between the memories and registers of the CPU, or central processor, and the coprocessor. Once the data is available in the QMP, quantum computing can take place.
Traditional quantum computing involves "qubits", where a quantum circuit represents a single bit and quantum arithmetic operations are similar to digital arithmetic operations. The primary innovative aspect of the QMP is the "qureal" where a single quantum circuit represents a real number. The five basic arithmetic operations of addition, subtraction, multiplication, division, and square root, can be carried out instantaneously, according to the rules of real arithmetic.
Quantities are stored in qureal registers and qureal memory as real numbers. There is no representation error. Arithmetic operations are carried out exactly. There is no roundoff error. Arithmetic operations are done instantaneously. If it could be measured, the execution time of an addition or multiplication operation would be found to be zero.
Heisenberg's uncertainty principle implies that it is not possible to access an infinitely precise real number in finite time. It would take an infinite amount of time, for example, to access the binary or decimal representation of a real result.
The programming environment of the QMP is based on MATLAB. The beta release of the environment is an implementation of what is now called "classic MATLAB", the simple interactive matrix calculator that I developed before we started MathWorks. The available features include basic MATLAB matrix management and command processing. Each of the following functions has been implemented as a single QMP instruction, so it is executed essentially instantaneously on a matrix of qureals.

This processor can solve a system of simultaneous linear equations instantaneously. Does that qualify the QMP as the faster computer in the world? My colleague Jack Dongarra and the other folks running the top 500 list will have two concerns when we submit our benchmark results. First, we can't access the computed solution in zero time. And, second my program is written in MATLAB, not Fortran.
