Quantum Computing and Superposition

• Quantum computers utilize quantum mechanics to perform calculations.
• They can achieve speeds that are unattainable by even the top supercomputers.

Quantum Computing vs Classical Computing

• Classical computers assess each possible move one at a time, and this can be time-consuming.
• Quantum computers simulate all possible moves at once which is much faster.
• Quantum computers can process information in a fundamentally different way than binary bits.
• Quantum computers can potentially revolutionize the future of technology.
• Classical and quantum computers both have circuits, chips, and logic gates to process information.
• Algorithms operate both types of computer.
• Classical computers use binary bits of 0s and 1s to represent the on/off state of a current.
• Quantum computers use qubits, which can exist in both states simultaneously, known as superposition.

Superposition

• Qubits can exist in both the 0 and 1 states simultaneously.
• A system of multiple qubits can simultaneously possess multiple states.
• Quantum computers can process many solutions simultaneously, which classical computers cannot do.
• This capability enables quantum computers to solve problems much faster than classical computers.

Quantum Entanglement

• The multiple states of multiple qubits can be linked (entangled) to each other.
• Operations of one qubit can influence other qubits, no matter how far apart they are.
• Entangled qubits can influence the entire system.
• Entanglement allows for significantly higher computational power.

Quantum Computer Appearance

• Quantum computers look like large, complex machinery, much like a chandelier, with golden, silver, and blue parts.
• Around the machinery is a maze of wires, tubes, and other intricate components.

Quantum Computer Advancements

• Some tech companies possess operational quantum computers that serve as valuable resources for software development and programming languages.
• In October 2019, Google asserted that it had achieved quantum supremacy with its quantum computer.
• Google used its specialized Sycamore processor to perform a specific type of computation much faster and more efficiently than the most powerful classical supercomputer.
• This validated that quantum computers can indeed surpass classical computers in specific tasks.
• Quantum computers can execute operations that classical computers cannot.
• This prompted other companies, such as Microsoft, IBM, and several startups, to intensify their quantum research.

Quantum Computer Potential

• Quantum computers have immense computational capabilities that will greatly enhance artificial intelligence.
• Quantum cloud computing services have the potential to revolutionize machine learning.
• The revolution would be due to the processing of extensive amounts of data and complex calculations at unprecedented speeds.
• Quantum computers could uphold data encryption during active use, providing robust protection in cybersecurity.
• They are poised to revolutionize medical and drug research, weather forecasting, and automobile battery technology.
