Introduction to Quantum Computing
What is ‘Quantum’?
Over the 1920s, Physicists found that light was equally well described by waves and particles. The theory of Quantum Mechanics was born out of studies of how these light ‘Quanta’ (discrete, quantized particles) behave. The Physicist Werner Heisenberg later proposed that subatomic particles all behave how waves would (oscillating and spreading over an area), until they interact with their surroundings or are seen by an observer. This surprising description of reality predicts that particles can be in a ‘superposition’ of being present and not present at a point, highlighted in Schrödinger's famous dead and alive cat paradox.
Figure 5: N. Hanacek, No Date, Quantum Physics & Superposition (Illustration), Available at: Quantum Physics & Superposition (Illustration) (nist.gov) (Accessed 25.09.23).
The skatepark in Figure 1 (above) is initially in a superposition state, where the skateboarder is on the left and the right side at the same time. Once the eye views the skatepark, its true state is revealed.
Now, if two quantum particles are both in superposition, and knowing the state of one determines the state of the other, then the two are said to be ‘entangled’. These phenomena are used heavily in Quantum Computing. If say, the two skateboarders in Figure 2 (below) always happen to be found on the same side of their own skateparks, then when a measurement is made on the first skatepark, the state of the other is immediately known.
Figure 6: Entanglement Visualization
These two phenomena are examples of the mysterious way in which elementary particles are consistently seen to behave (note: everydaymassivematter behaves this way too, although due to its size, it interacts with its environment very easily. This ease of ‘decoherence’ means that quantum behaviour is practically negligible). Thus, ‘quantum’ refers to anything related to objects behaving under Quantum Mechanics.

Figure 4 represents Schrödinger's analogy of the absurdities of superposition with a ‘dead and alive’ cat inside the blue box is a particle which has a probability of decaying and not decaying. If the particle decays, then the red ball is released and breaks open the poison jar. Although impossible, from Philosophical interpretations of superposition, the cat would also enter the dead and alive state, with probabilities corresponding to that of the particle decaying and not decaying.
What is Quantum Computing?
Classical computers such as the one you are using right now take as input a sequence of digits (0s and 1s, known as a binary string) and produce an output sequence of digits by using an ‘algorithm’ on this binary string. We get computers to recognize these digits through creating Physical bits, which can represent a ‘yes’ or a ‘no’. An example of this is the Compact music disk, which has troughs and flat sections. A computer detects a trough and reads it as a 1, and a flat section as a 0. Through this process it converts a piece of music into binary for a speaker to play.

The operations that computers use to create an output is represented using circuit diagrams, which take as input bits (0s or 1s). An example of a circuit diagram is shown in Figure 6 (below). This circuit is made of an ‘XOR’ gate, which outputs a 1 only if the two input values are different (e.g., a 1 output if the two bits are 0 and 1).
Figure 9: WatElectronics.com, 2023, XOR Gate, Available at: Logic Gate: Types including Circuit Diagram, Symbols and Uses (watelectronics.com) (Accessed 25.09.23)
Interestingly, if these classical bits behaved in a superposition of states, that is they could occupy a 0 digit and a 1 digit simultaneously, then the number of combinations of binary strings able to be made from these bits would be significantly greater than if this behaviour weren’t present. This kind of advantage led Physicists Richard Feynman and Yuri Manin in the 1980s to propose the idea of ‘Quantum Computers’, who take as input ‘Qubits’ (quantum bits).
The gates used in quantum computers are designed specifically to work on qubits. They take as input what is called a ‘State vector,’ a list (or vector) of values representing the probabilities of finding the qubits in a particular state, due of superposition, entanglement, and other quantum phenomena. For example, the state for a 1 is: 1> = [0, 1], where the '>' symbol is called a Ket. Other 'operations' in quantum computing use Bra '<' symbol. Braket notation is used to write all of the mathematics involved with Quantum Computing. The table below shows a comparison of gates acting on bits.

An interesting result of all quantum gates, which is only present in a few classical gates, is that they are reversible when the gate is applied again to a State vector output, it returns the input qubit state. This result enables information to be preserved, which is incredibly useful for transferring results between quantum circuits. Aside from increased capacity for transferring information, quantum gates also come in varieties not found in the world of classical computing. An example of such a gate is a Hadamard gate which, when applied to a single qubit, produces a superposition state that is, the resultant State vector is a superposition between the states 0> and 1>.
Figure 10: Wikipedia, No Date, Hadamard Gate, Available at: File:Hadamard gate.svg  Wikipedia, (Accessed 25.09.23)
The Hadamard gate has been used to design quantum algorithms, such as the DeutshJotsza and Simon’s algorithm, that have been proven to outperform classical algorithms.
Why Quantum Computing?
The phenomena of entanglement and superposition, among others allow quantum algorithms, made up of quantum specific gates, to outperform classic computers vastly in so called ‘intractable problems’. Intractable problems, common in the real world, are problems whose computing time increases exponentially with input size (see Figure 9). As quantum computers’ total storage for n bits increases exponentially, among other reasons, has led to Quantum Computers being proven to solve intractable problems in short amounts of time, such as a team at USTC demonstrating a solution to a problem in 200 seconds on a Quantum Computer that would have taken a supercomputer 2.5 Billion years.

Learning Quantum Computing from Scratch (Qiskit)
Recently, online Cloud access to quantum computers has become available, allowing tens of thousands of students and technology enthusiasts to freely experiment with a cuttingedge technology. Organizations such as IBM (through Qiskit), Microsoft Azure and Google AI Quantum have all developed their own online learning resource notebooks, which teach enthusiasts to use quantum algorithms using common programming languages such as Python. This has encouraged waves more of online communities and resources to be made, forming a burgeoning online quantum community.
Current Challenges in the Industry
In an ideal world, with Google AI Quantum and USTC both having reached quantum supremacy, organizations will be proactive in becoming quantum aware and ready for the imminent paradigm shift towards a future of quantum advantage. However, in 2022, Ernst and Young’s Quantum Readiness survey revealed that whilst 97% of executives expected Quantum Computing to cause industry disruption, less than 33% of their businesses had begun the strategic planning necessary to prepare for its technological commercialization. This lack of focus will create a wide educational divide, which will exacerbate the present socioeconomic gap within the next decade. Quantum ignorance will cause massive misuse of quantum technology and immeasurable disruption to existing, classical industries, thereby affecting everyone, everywhere.
QTopia> plans to mitigate this issue by spreading quantum awareness to drive progress towards a multidisciplinary quantum computing future through its gamified and interactive learning approach, alongside collaborative initiatives organised with leading quantum organizations such as IBM.
