Hardware of a Quantum Computer #9 Summary

• Quantum Chip → need physical qubits
  • controlled to a superposition state
  • coupled together to create entanglement
• Spin qubits in quantum dots - very dense and coherent systems
• NV centers in diamond - efficiently coupled and manipulated via photons
• Superconducting qubits - one of the most advanced platforms today
• Topological qubits - much lower sensitivity to noise
• Today’s quantum devices require individual electronics and connects for each and every qubit
  • increasing to large number will require a different scaling law
    • e.g. crossbar layouts, signals only have to come from the sides to address a large array
  • functionality of a quantum system
    • number of qubits available
    • amount of operations that can be executed
• Quantum supremacy : era where quantum systems become too complex to be efficiently simulated with classical computers

배경지식의 한계로 50%도 이해 못한 것 같지만… 여러가지 양자컴퓨터의 가능성에 대해 알게된 것 만으로도 만족한다ㅎㅎ 수료했당
