Quantum Computers and Why They Matter

Computers are classified into three main types:

• Analog: Utilise mechanisms such as gears and pulleys to assist in computations, defined as making calculations or determinations through mathematical equations or reasoning.

• Digital: Use semiconductors to process information in binary code (1s and 0s), conducting calculations based on data sets.

• Quantum: Employ physical atoms to perform all possible calculations at once.

The unique advantage of quantum computers lies in their ability to leverage the probability of solutions to deduce the most likely outcomes rapidly. This capability allows quantum computers to handle vast datasets effectively, surpassing the capabilities of digital computers in areas like:

• Search Engines: Efficiently processing enormous amounts of data.

• Optimization: Enhancing efficiency and profitability.

• Simulations: Addressing complex issues beyond digital computers’ reach.

• Artificial Intelligence: Increasing prediction accuracy by learning through trial and error.

Quantum computers have not yet reached their full potential, but they are set to aid in managing the massive data sets accumulated globally, particularly vital in an era deeply reliant on data.

This month I chose to read “Quantum Supremacy” by Michio Kaku. Although I’m only a few chapters in, the book has sparked numerous questions. It’s evident that technologists appreciate that quantum computers are:

• Extremely Fast: Approximately 100 trillion times faster than an ordinary supercomputer.

• Atomic/Nuclear: Performing computations at the atomic level.

• Simultaneous: Analyzing all possible paths concurrently.

• Publicly Accessible: IBM Q offers 15 publicly accessible quantum computers for free.

Kaku emphasizes that quantum computers are not intended to replace humans but to empower those who use them to lead in the quantum age.

The importance of this lies in the fact that natural processes operate on quantum mechanical principles. Processes such as photosynthesis and human cell regeneration harness quantum mechanics’ power to rejuvenate environments and heal life, and in some perspectives, this power elevates humanity toward god-like capabilities.

Today, in the United States, citizens are voting between leaders with starkly different ideologies. Regardless of the outcome, the U.S. will persist in its quest for quantum supremacy, alongside Russia, China, and Iran. These nations, while often seen as primary contenders, are part of a global competition for quantum leadership.

Historically, when the world seemed smaller, communication occurred within villages that exchanged news and resources. As populations grew and territories clashed, conflicts over resources became inevitable, often leading to slavery, imprisonment, or death for the losing groups.

Over time, human knowledge advanced, fostering improved resource-sharing practices. However, resource scarcity continues to incite conflict. The ongoing battle over supply chain control is old, yet ensuring equitable access to essential resources remains critical. Revisiting fundamental lessons of sharing from childhood could pave the way towards using quantum computers for optimizing supply chains efficiently for everyone’s benefit.
