Abstract

Quantum mechanics explains the behavior of matter and its movement with energy in the scale of atoms and subatomic particles. In quantum circuits there are many gates such as Hadamard Gate, Pauli Gates, many more gates for half turns, quarter turns, eighth turns, sixteenth turns and so on, rest for spinning, parametrized etc. Linear operators in general and quantum mechanics can be represented in the form of vectors and in turn can be viewed as matrices format because linear operators are totally equivalent with the matrices view point. This paper discloses creation of various quantum matrices using Quantum bits. Square, Identity and Transposition of matrices are performed considering whole process in entanglement. Angle, phase, coordinates, magnitude, complex numbers and amplitude has been noted and documented in this paper for further research.

Introduction

In physics, the size of iotas (atoms) and electrons demonstrates that how things move at every day at different sizes and speeds. In classical mechanics, objects exist in a definite place at a definite time. However, in quantum mechanics, objects rather exist in a haze of probability; they have a specific possibility of being at point A, another chance of being at point B. Certain properties like position, speed and colour can sometimes occur in exact, set amounts, like a dial that “clicks” from number to number. This challenged a fundamental assumption of classical mechanics, which said that such properties should exist on an even, continuous spectrum. To illustrate the possibility that a few properties “clicked” like a dial with definite settings, experts coined the word “quantized” [1].

Beam Splitter

An example was demonstrated by Prof. Marek Perkowski from Portland State University using beam splitter and based on that how quantum circuits could work. “Half of the photons leaving the light source arrive at detector A; the other half arrive at detector B” [2,3] (Figure 1 & 2).

figure 1: Demonstrates the light beam splitting to two directions [3].


figure 2: Demonstrates simplest circuit of light beam splitter in Quantum Circuit [1].


Linear Algebra in Quantum Mechanics

The most convenient way to understand linear operators is in terms of their matrix representations. In fact, the linear operator and matrix viewpoints turn out to be entirely equivalent. For more information on linear operator representation can refer Reference No 7

Vectors can be written as:

For readability format it can be written as (1,2) and for two level quantum systems used as qubits, we can identify the state |0” with the vector (1, 0), and similarly |1” with (0, 1) [4-6].

Square Matrices using Quantum Gates

A simulation was performed on Hadamard Gates to generate square matrices considering entanglements of quantum bits [7].

2. Real value of each quantum bit is equal for all quantum bits and for every addition of two quantum circuit there is a decrease of real value by half

3. Magnitude of each quantum bit decreases by half for every addition of quantum circuit (In this case one fourth because addition of two circuits)

Observations from transposition of matrix

1. Successfully performed transposition of matrix utilizing sixteen (max) quantum circuits considering entanglement process using Hadamard, Pauli X and NOT gates

2. Magnitude and phase don’t change in transposition of Matrix

3. Magnitude of each quantum bit decreases by half for every addition of two quantum circuit

4. Graphs of twelve, fourteen and sixteen quantum circuits are not used due to complexity of the circuit and limitation of the tool to process large quantum circuits

5. Tables of eight, ten, twelve, fourteen and sixteen quantum circuits are avoided due to limitation of the tool to process large quantum circuits.

Applications of Quantum Matrices

1. Quantum Matrices can be used to solve system performance with a big RAM and/or a high clock rate for Quantum Central Processing Unit (QCPU)

2. Studying Quantum Matrices and their properties is of crucial importance in trying to improve linear solvers efficiency in Quantum Processor/Quantum computer

3. If constructing a larger system in a quantum processor with the same pattern (2 on the diagonal, -1 on the upper and lower diagonal) and put a right-hand side with only positive entries, we can still claim that the solution exists and it’s positive and the number of operations needed to solve it, where n is the size of the system [7].

Results

What claimed are

1. Successfully processed 65536 quantum bits of information for 16 quantum circuits to achieve square matrix considering whole process in entanglement

2. Square matrix for quantum bits is generated with respect to phase, angle, complex values and magnitude of the results

3. Successfully processed 256 quantum bits of information for identity matrix and transposition of matrix with respect to phase, angle, real, complex values and magnitude.

4. Identity matrix for quantum bits is generated with respect to phase, angle, complex values and magnitude of the results.

5. Transposition of matrix for quantum bits is generated with respect to phase, angle, complex values and magnitude of the results.

6. Study of Hadamard Gates are performed and observations are noted.

7. Study of various phases, angles, complex values, magnitudes and amplitudes of the quantum bits are performed and is documented in this paper

8. Based on results and above data other matrices such as row matrix, column matrix, rectangular matrix, diagonal matrix, scalar matrix, triangular matrix, null matrix can be constructed using quantum bits.
