#キャルちゃんのquantphチェック 変分量子アルゴリズム(VQA)応用のために、4準位超伝導quditを用いて2量子ビットエミュレータを実装、さらにそのノイズモデルを解析。VQAの主なエラー源が読み出しによる誤分類エラーと振幅減衰であることから、これを軽減する誤り緩和を適用。 https://t.co/yW2TQyzPXw https://t.co/xS8goVhD4X

Four-level qudit mimicking two qubits is as good & scalable as encoding n qubits in 2^n levels of infinite dimensional harmonic oscillator https://t.co/sfGxnx3Qer It does not look like a solution for scalability or smart encoding, unless system to simu
