What is the physical form of binary data in a computer processor?

In summary: However, in digital circuits, current is used to encode binary data. It is used to control the flow of electricity in order to create a desired output.

This a general, layman question. Computer processors work with binary digits, 1 and 0. Of course, computer processors can be seen as microscopic forms of Babbage's analytic engine. So in reality, in the circuits of a microprocessor, what physical form do binary digits take?

High and low voltage in circuits.

what about on/off currents? Though, I've heard that binary in newfangled quantum computers corresponds to excited and de-excited states of atoms.

No, not in typical digital logic circuits. Voltage levels are used to encode the binary data.

Quantum computers will use different mechanisms, right. There is no quantum computer processor yet.
Current is problematic to control (it would always depend on sender AND receiver of data).

what about the one from D-Wave?

Processors also include "tables" of data for certain operations, so in addtion to voltage levels, binary data is represented by the presence or absence of connectors or diodes used to change a set of voltage inputs into a particular combination for output from a table.

Is that more than an announcement?
Their flux qubits would use the direction of current flow (or, equivalently, the direction of a magnetic field) to decode 0, 1 and superpositions of those.

the sort of digital logic circuits found in most PCs?
In all.

what sort of circuits use current?
Well, current can correspond to data in analog circuits.
 

1. What is binary data?

Binary data is a type of data that consists of only two possible values: 0 and 1. It is the fundamental data form used by computers to represent and process information.

2. How is binary data stored in a computer processor?

Binary data is stored in a computer processor using a series of on and off electrical signals, which are represented as 0s and 1s. These signals are organized into binary code, with each code representing a different character or instruction.

3. What is the physical form of binary data in a computer processor?

The physical form of binary data in a computer processor is a series of tiny electrical switches called transistors. Each transistor has two states, on and off, which correspond to the binary values of 1 and 0.

4. How does a computer processor interpret binary data?

A computer processor interprets binary data by following a set of instructions, known as machine code, which tells it how to process and manipulate the data. These instructions are represented by different combinations of 0s and 1s.

5. What is the relationship between binary data and computer memory?

Binary data is stored in computer memory as a series of bits, which are the smallest units of data in a computer. These bits are organized into bytes, which can hold 8 bits of data, and are then used to represent larger units of information, such as characters or numbers.
