Quantum computing was first proposed to improve physics simulation in the 1980s. For example, quantum simulators have already been built with a much larger number of physical qubits than general-purpose quantum computers, but the gap is starting to narrow. ### What is quantum computing? It included the concepts of quantum logic gates and qubits for quantum computing and established the theoretical framework for quantum algorithms and processors. Meanwhile, researchers in the U.S. and Germany made progress in scaling NMR quantum computers to seven qubits capable of using Shor's algorithm for simple problems. In 2003, the field began to diversify as researchers demonstrated quantum computers built on new physical phenomena that use trapped ions and photons. It sped up certain optimization problems and guided research on quantum annealing algorithms for simulation, but it did not show cost or performance advantages over classical computers. Considerable progress has been made in developing quantum computers and algorithms in the last several decades.

# The History of Quantum Computing You Need to Know [2026]. In this article, we’ll take a look at the **history of quantum computing**, from its earliest beginnings to the present day. ## Why Bother Learning About Quantum Computing History? transistor as a base of quantum computing. microprocessors before the quantum computers. ## Quantum Computing Timeline. Today’s quantum computers are described by some as sitting around the vacuum tube era (or before) as we outlined above in the previous section. **How does the history of classical computing relate to where quantum computing stands today?**. The article traces computing from vacuum tubes and transistors to microprocessors, noting that further miniaturization has forced engineers to confront quantum mechanical effects like electron tunnelling. Today’s quantum computers are compared by some to the vacuum tube era — powerful in potential but still early and unreliable. **What broader lesson does the history of classical computing offer for quantum’s future?**. ### 12 Top Quantum Computing Universities in 2025.

# Quantum Computing History: Path to Pasqal. From Bohr’s quantum atom model to Feynman’s visionary proposal for quantum computers, each milestone built upon the last, gradually transforming theoretical quantum mechanics into practical computing technology. Pasqal stands at the culmination of this remarkable scientific journey, particularly the transformative advancements in neutral atom quantum computing pioneered at Institut d’Optique. ### Neutral Atom Quantum Computing Takes Shape. Thierry Lahaye and Antoine Browaeys demonstrated high-fidelity quantum operations with neutral atoms, achieving precise quantum state manipulation and measurement with error rates low enough for practical quantum computing. Antoine Browaeys, Thierry Lahaye, and their team at Institut d’Optique demonstrated unprecedented control of large arrays of neutral atoms with programmable interactions, showing their viability for quantum simulation and computing. Their groundbreaking work proved that neutral atom platforms could perform complex quantum operations with high precision while maintaining excellent scalability, creating the scientific foundation for Pasqal’s quantum computing approach. Pasqal was established to commercialize neutral atom quantum computing technology, building directly on the pioneering research at Institut d’Optique.

# The U.S. Must Win the Quantum Computing Race. But this isn’t the first quantum race in history that pitted the U.S. against its adversaries—and the past provides a guide for how the U.S. can win the coming computing revolution. The technologies born from the first quantum revolution were at the core of American national defense, and also reshaped civilian life in the U.S., most especially through the development of personal computers and the Information Revolution. In the past 10 years, private technology companies such as IBM, Google, and Microsoft have made significant investments in quantum computing, which have pushed the field to new heights of maturity and accelerated a global race for quantum dominance — one with major national security and cybersecurity implications. An error-correcting quantum computer would launch the second quantum revolution, and a race is on to preserve the U.S.’s leadership in science for one of the 21st century’s most prized technologies.
