Can computing continue to improve?
What is Moore's law?
What's the issue?
- "Such Moore scaling now requires ever-increasing efforts, stimulating research in alternative hardware and stirring controversy" (Markov).
- "At some point, Moore’s law must break down" (Lloyd 1).
- "Intel has suggested silicon transistors can only keep shrinking for another five years" (Simonite).
- "First, most of the energy is locked up in the mass of the particles of which the computer is constructed, leaving only an infinitesimal fraction for performing logic" (Lloyd).
- "Second, a conventional computer employs many degrees of freedom (billions and billions of electrons) for registering a single bit" (Lloyd).
- "conventional designs rely on redundancy for reliability and manufacturability" (Lloyd).
- “using channel materials with an anisotropic effective mass, the channel can be scaled down to 1 nm and still provide an excellent switching performance in phosphorene nanoribbon MOSFETs" (Ilatikhameneh).
- Aside from classical computing quantum computing also appears to be promising
What about quantum computing?
- A processor called Sycamore took 200 seconds to complete a task that would take a supercomputer an estimated 10,00 years (Arute)
- Quantum computing aims to solve some problems exponentially faster than a classical computer (Arute)
- "Redundancy is not required by the laws of physics: recently constructed quantum microcomputers use one quantum degree of freedom for each bit and operate at the Heisenberg limit ... for the time needed to flip a bit" (Lloyd).
- "prototype quantum computers that store and process information on individual atoms have already been demonstrated" (Lloyd).
