Introduction


Quantum computing is an advanced computational paradigm that leverages quantum mechanics to process information in fundamentally different ways than classical computing. Important concepts within this field include quantum states, Bell states, quantum teleportation, and quantum gates. This report aims to explore some fundamental aspects of quantum computing, particularly focusing on the measurement of Bell states, the teleportation of qubits, the design of a full adder quantum circuit, and demonstrating the orthonormality of the column vectors of the Hadamard matrix.

1. Measuring the Bell State \( |\Phi^+\rangle = \frac{1}{\sqrt{2}} (|00\rangle + |11\rangle) \) in the \( \{ |+\rangle, |-\rangle \} \) Basis


The Bell state \( |\Phi^+\rangle = \frac{1}{\sqrt{2}} (|00\rangle + |11\rangle) \) is one of the four maximally entangled states that can be formed from two qubits. To measure this state in the basis \( \{ |+\rangle, |-\rangle \} \), where \( |+\rangle = \frac{1}{\sqrt{2}} (|0\rangle + |1\rangle) \) and \( |-\rangle = \frac{1}{\sqrt{2}} (|0\rangle - |1\rangle) \), we can express the Bell state in terms of the new basis.
1. The state \( |00\rangle \) can be written as:
\[
|00\rangle = |+\rangle|+\rangle + |+\rangle|-\rangle - |-\rangle|+\rangle - |-\rangle|-\rangle
\]
Therefore,
\[
|\Phi^+\rangle = \frac{1}{2} \left( |+\rangle|+\rangle + |+\rangle|-\rangle - |-\rangle|+\rangle - |-\rangle|-\rangle \right)
\]
2. When measuring the first qubit in the \( \{ |+\rangle, |-\rangle \} \) basis, the probabilities are given for different outcomes:
- The probability of measuring \( |+\rangle \) is \( \frac{1}{2} \).
- The probability of measuring \( |-\rangle \) is also \( \frac{1}{2} \).
Thus, on measuring the Bell state \( |\Phi^+\rangle \), the measured output can yield either \( |+\rangle \) or \( |-\rangle \) with equal probability \( \frac{1}{2} \).

2. Quantum Teleportation of a Qubit


Quantum teleportation is a process by which quantum information can be transmitted from one location to another without moving the qubit itself. In this scenario, Alice and Bob share the Bell state \( |\Psi\rangle = \frac{1}{\sqrt{2}} (|01\rangle + |10\rangle) \), and Alice has a qubit \( |\psi\rangle = a|0\rangle + b|1\rangle \) that she wishes to send to Bob.
The steps for Alice to teleport her qubit to Bob are as follows:
1. Prepare the Combined State:
The initial combined state can be expressed as:
\[
|\text{Total}\rangle = |\psi\rangle \otimes |\Psi\rangle = (a|0\rangle + b|1\rangle) \otimes \left(\frac{1}{\sqrt{2}}(|01\rangle + |10\rangle)\right)
\]
2. Entanglement Swapping and Measurement:
Alice performs the Bell-state measurement on her qubit and her portion of the entangled state. This results in one of the four possible Bell states, which then determines the state Bob will have.
3. Classical Communication:
Alice sends the results of her measurement (two classical bits) to Bob.
4. Bob’s Transformation:
Depending on Alice’s measurement result, Bob performs specific operations on his qubit to convert it to the state \( |\psi\rangle \). For example:
- If Alice measures \( |01\rangle \), Bob does nothing to his qubit.
- If Alice measures \( |10\rangle \), Bob applies an X-gate to his qubit.
Thus, the state \( |\psi\rangle \) has been effectively teleported to Bob.

3. Designing a Full Adder Quantum Circuit


A full adder circuit can be implemented using Toffoli gates and CNOT gates. A full adder computes the sum and carry output for three input bits: \( A, B, \text{ and Carry In (Cin)} \).

Quantum Circuit Design


1. Inputs:
- Input bits \( A \), \( B \), and \( C_{in} \).
2. Outputs:
- Sum \( S \) and Carry Out \( C_{out} \).

Circuit Implementation Steps


1. Use Toffoli Gates:
- Compute carry-out:
\[
C_{out} = A \cdot B + (A \oplus B) \cdot C_{in}
\]
- Using a Toffoli gate, the first Toffoli gate computes \( C_{out} \) from \( A \), \( B \), and \( C_{in} \).
2. Compute Sum:
- The sum can be computed with CNOT gates:
\[
S = A \oplus B \oplus C_{in}
\]
- Use CNOT gates to compute the final sum.
This results in a circuit that correctly calculates the sum and carry of the three bits.

4. Orthogonality of Hadamard Matrix Columns


The Hadamard matrix \( H_n \) for \( n \) qubits is defined recursively:
\[
H_n = \frac{1}{\sqrt{2}} \begin{pmatrix}
H_{n-1} & H_{n-1} \
H_{n-1} & -H_{n-1}
\end{pmatrix}
\]
To show that the columns of \( H_n \) are orthonormal, we need to demonstrate that:
1. The dot product of different columns is 0 (orthogonality).
2. The norm of each column is 1 (normalization).

Proof Sketch


Assuming the columns of \( H_{n-1} \) are orthonormal:
1. Columns of \( H_n \) are formed by adding and negating columns of \( H_{n-1} \).
2. The dot product of two different columns composed from \( H_{n-1} \) results in sums that cancel out due to symmetry.
Combining the two steps shows that the columns remain orthonormal, hence proving that every \( H_n \) maintains orthonormal columns.

Conclusion


This report delved into fundamental aspects of quantum mechanics, facilitating a deeper understanding of Bell states, quantum teleportation, and quantum gate functionalities. Quantum computing's unique properties have the potential to revolutionize computation, security, and information transfer in the future.
