[❮News](https://www.lerner.ccf.org/news/)[Researchers design new quantum error correction strategies](https://www.lerner.ccf.org/news/article/?title=Researchers+design+new+quantum+error+correction+strategies&id=14f1e822ddfd0868e1e85de74ecca7895b8858e7). One of the last steps in achieving quantum computing’s potential is developing quantum error correction methods.Researchers in Cleveland Clinic’s [Center for Computational Life Sciences](https://my.clevelandclinic.org/research/computational-life-sciences) (CCLS) are taking on the challenge of creating new methods to ensure accurate results from quantum computations. [Ahmet Erdemir](https://www.lerner.ccf.org/biomedical-engineering/erdemir/), PhD, CCLS Associate Staff, says when it comes to quantum computing, we are still in the critical beginning stages of applying quantum computing to research problems. CCLS’ [Daniel Blankenberg](https://www.lerner.ccf.org/computational-medicine/blankenberg/), PhD, CCLS Assistant Staff, and Bryan Raubenolt, PhD, a postdoctoral fellow, are working on a hybrid model that applies a mix of quantum and classical computing methods to ensure accuracy. In [collaboration with IBM](https://my.clevelandclinic.org/research/computational-life-sciences/discovery-accelerator), Drs. Blankenberg and Raubenolt are creating a framework to [accurately predict the structure of proteins](https://www.lerner.ccf.org/news/article/?title=Cleveland+Clinic+and+IBM+researchers+apply+quantum+computing+methods+to+protein+structure+prediction&id=adbed13da81d74850350f76d9e125b3eb23121d8) by treating it as an optimization problem for the quantum computer to solve. A team led by [Kenneth Merz](https://www.lerner.ccf.org/computational-medicine/merz/), PhD, is taking another approach: implementing error correction using a classical computer after running the initial calculations on a quantum computer.

# What Is Quantum Error Correction: The Key to Quantum Computing. ## What Is Quantum Error Correction? Entangling these qubits helps detect and correct quantum errors without having to directly measure the qubits’ states. ## Types of Quantum Error Correction. Advanced quantum error-correcting codes, such as the Shor code, are designed to correct bit-phase flip errors by encoding the logical qubit in a way that protects it from all common types of quantum errors. QEC allows quantum systems to pinpoint and correct errors without directly measuring qubit states. Building hardware and software systems that can carry out error correction accurately without adding noise is a key challenge for reliable quantum computing. On top of that, making sure that error correction works hand-in-hand with quantum computations requires advancements in both hardware and algorithm development. ### What is quantum error correction? Quantum entanglement error correction uses the entangled state of qubits to detect and fix errors in a quantum system without collapsing their quantum state.
