An Introduction to Quantum Computing
"We are analog beings living in a digital world, facing a quantum future."
-- Neil Turok
Quantum Computing
Many times experts fail because they are experts in the past version of the world.
The future of quantum computing is incredibly exciting. With its potential for near-instantaneous computation and processing power, quantum computing could revolutionize the way we interact with data and could have a major impact on virtually every industry. Quantum computers are already being used in chemistry, material science, pharmaceuticals, robotics and finance. In the coming years, they are expected to become even more widely used as the hardware and software advances. The possible applications for quantum computing seem almost limitless – from solving complex problems to predicting weather more accurately than ever before.

Google's Marissa Giustina addresses some basic questions about quantum computing. You’ll learn about what makes a quantum computer “quantum”, and what differentiates it from a classical computer. In addition, you’ll get to see what Google’s current quantum processors look like, and see the stack of hardware infrastructure needed to run the full system.
- What does it mean for hardware to be quantum?
- What differentiates quantum hardware?

The Osprey chip, developed and built by IBM Quantum, is the largest Quantum Computer made to date. We sit down with Jerry Chow, Director of IBM Quantum hardware, to ask him how the team went about developing Osprey, what challenges had to be overcame to do so, and the future of quantum technology.
"Quantum computers aren’t the next generation of supercomputers—they’re something else entirely. Before we can even begin to talk about their potential applications, we need to understand the fundamental physics that drives the theory of quantum computing."
