Exploring the Possibility of "Phantom" Computers: How Small Can We Go?

  • Thread starter leftyguitarjo

In summary, computers are continually becoming smaller in size and now we have quantum computers that use elementary particles for calculations. It is uncertain when we will reach the smallest possible size for computers, and there is a possibility of a "phantom" computer made of unconventional matter. The exact size of these computers is difficult to determine as our current understanding of the smallest particles may change, but an absolute size would be the Planck length.

computers today are getting smaller and smaller. Now we have developed quantum computers, using elementary particles perform calculations. When do you suppose we will hit a point where we get computers as small as we can get them? How small will they can possibly be?

Is there a possibility we'll have a "phantom" computer, not made of conventional matter, like in Issac Asimov's "The Last Question"

EDIT: I'm sorry, I did not notice the computer section until after I posted this.

It's hard to put a size to this as I guess what we think are the smallest known particles may not be findamental and so may open up a whole new range of possibilities.

Of course, if you need an absolute number for this question, it would be the Planck length.
 

What is the definition of a "phantom" computer?

A "phantom" computer is a theoretical computer that takes up no physical space and can exist purely in the digital realm. It is also known as a "virtual" or "invisible" computer.

What is the current smallest computer in existence?

The current smallest computer is the IBM Z10BC, which measures 0.5 x 0.5 millimeters and is about the size of a grain of rice. However, it is not a true "phantom" computer as it still takes up physical space.

What are the potential benefits of creating "phantom" computers?

Creating "phantom" computers could allow for more efficient use of space and resources, as well as increased computing power and speed. It could also lead to advancements in fields such as medicine, transportation, and communication.

What are the challenges involved in creating "phantom" computers?

One of the main challenges is developing technology that can operate on such a small scale without being affected by external factors such as heat or radiation. Another challenge is finding ways to power and cool these tiny computers. Additionally, there may be ethical concerns about the potential consequences of creating "phantom" computers.

How close are we to achieving "phantom" computers?

The technology for "phantom" computers is still in its early stages, and there is no definitive answer to how close we are to achieving them. However, with advancements in nanotechnology and miniaturization, we are getting closer to making them a reality.
