What Are Quantum Chips?
Quantum chips power quantum computers using qubits—units that differ fundamentally from classical bits. While classical bits are binary (0 or 1), qubits can exist in superposition, representing both 0 and 1 at once. This enables quantum systems to process immense data sets and solve high-dimensional problems much faster than traditional computers.
Key Challenges:
Qubit Stability (Decoherence): Qubits are extremely sensitive to noise and environmental changes.
Error Correction: Quantum error correction is vital, but difficult to scale.
Hardware Limitations: Specialized cooling systems and complex environments drive up cost and complexity.
