Quantum computing does use binary code at its core, but with a crucial twist that makes it fundamentally different from classical computing.
1. Binary in Classical Computing
- All data and instructions are ultimately represented in binary code.
- Classical computers store and process information in bits.
- Each bit is either 0 or 1 (binary).
2. Binary in Quantum Computing
- Quantum computers use qubits (quantum bits) instead of classical bits.
- A qubit can be in state |0⟩, |1⟩, or a superposition of both (e.g., α|0⟩ + β|1⟩, where |α|² + |β|² = 1).
- Yes — the basis states are still labeled 0 and 1, just like binary.
- So quantum computing is built on a binary framework (two basis states), but extends it with quantum properties.
3. Key Differences
| Feature | Classical Bit | Qubit |
| States | 0 or 1 | 0, 1, or superposition |
| Measurement | Always 0 or 1 | Collapses to 0 or 1 probabilistically |
| Parallelism | None | Superposition enables massive parallelism |
| Entanglement | N/A | Qubits can be entangled |
4. Programming Quantum Computers
- You still write algorithms using binary logic gates (like NOT, AND, etc.), but they are replaced with quantum gates (e.g., Hadamard, CNOT).
- Input and output are binary strings (e.g., 10110), but during computation, the system explores all possible binary combinations simultaneously via superposition.
Summary
Yes, quantum computing uses binary code — qubits have two basis states (0 and 1), and all data is ultimately binary.
But it transcends binary logic through superposition, entanglement, and interference, enabling exponential computational power for certain problems.
Think of it like this:
Classical = black or white
Quantum = all shades of gray at once (until measured)
The symbol β (lowercase Greek letter beta) in the expression:
α|0⟩ + β|1⟩
represents beta — not omega.
Quick Clarification:
| Symbol | Name | Used For |
| α | alpha | Coefficient of |
| β | beta | **Coefficient of |
| ω | omega | Not used here (often for angular frequency or other variables) |
So yes — β is beta.
**No — quantum computing does *not* use the Greek letter ω (omega) in the standard description of a qubit’s state. **
Standard Qubit State (Dirac Notation):
A single qubit is written as:
|ψ⟩ = α|0⟩ + β|1⟩
- α (alpha) → complex coefficient for |0⟩
- β (beta) → complex coefficient for |1⟩
- Must satisfy: |α|² + |β|² = 1 (normalization)
Only α and β are used.
ω is not part of this.
Where ω Might Appear (Rarely & Not Standard):
| Context | Use of ω? | Meaning |
| Multi-qubit systems | Sometimes | Rarely used as a third coefficient in non-standard or pedagogical examples (e.g., for 3-level qutrits), but not for qubits |
| Quantum optics / harmonic oscillators | Yes | ω = angular frequency of light or oscillator |
| Phase estimation algorithms | Yes | ω may represent a phase or eigenvalue |
| General quantum states | Possible | In arbitrary notation, someone could use ω, but it’s non-standard and confusing |
Official Standard (Textbooks, IBM, Google, etc.):
- Single qubit: α|0⟩ + β|1⟩
- Two qubits: α|00⟩ + β|01⟩ + γ|10⟩ + δ|11⟩ (now using γ, δ — still no ω)
- Never ω for basis state coefficients in qubits
Summary Table:
| Symbol | Used in Standard Qubit State? | Purpose |
| α | Yes | Coeff of |
| β | Yes | Coeff of |
| ω | No | Not used |
Bottom line:
Quantum computing uses α and β for qubits — never ω.
ω appears elsewhere in physics, but not in the binary-like state of a qubit.
