Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Doretha Clemons, Ph.D., MBA, PMP, has been a ...

Quantum technology is moving from lab curiosity to commercial reality, and the shift is starting to redraw the boundaries of entire sectors rather than just speeding up a few algorithms. The next wave ...

The scale of investment in quantum computation, simulation and sensing is growing at a tantalizing pace. Harnessing the nanoscale to engineer useful quantum effects is a transformative capability of ...

For a future quantum internet to work, scientists need to perfect a quantum repeater that can send information over long ...

Quantum computing is a revolutionary form of computing that uses the principles of quantum mechanics to perform calculations that would be infeasible or impossible for classical computers. Unlike ...

The light interacts with the cavity and makes an arbitrary number of bounces before leaking out. This emergent light is traditionally treated as heat in quantum simulations. However, it can still be ...

Quantum technologies are shifting from frontier science to real-world applications. Around the world, governments and ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

The capability of qubits in a quantum computer to maintain their quantum mechanical state (their superposition state) over time. Otherwise, errors are generated. Maintaining this coherent state and ...

Everyone's racing to build the most powerful quantum computer. But what if the winner is the one that plays nicest with ...

The Big Ideas: What Is Reality? Effective theories in physics can help us measure and examine reality, despite the many things we do not yet know. By Lisa Randall Dr. Randall is a physicist. This ...
