As the world inches closer to a revolutionary shift in computing, quantum computers are at the forefront of this change. Yet, for scientists to effectively tackle the myriad challenges anticipated for future quantum systems, such as optimization issues, cryptography problems, or advancements in artificial intelligence , a formidable number of qubits will be necessary. Estimates suggest we may need several million qubits—or even hundreds of millions—to fully realize this potential. Currently, the most advanced quantum processor is held by IBM, which boasts just over a thousand qubits, highlighting the significant technological hurdles that remain to be surmounted.
Interestingly, there is no singular pathway towards enhancing quantum computing capabilities. Various organizations are exploring different technologies for qubits, each at varying stages of maturity. Major tech companies like IBM, Intel, and Google have heavily invested in superconducting qubits , while smaller firms such as Atlantic Quantum, IQM, Anyon Systems, Rigetti Computing, and Bleximo are also making strides in this domain.
The sheer number of companies working on this type of quantum bit suggests that superconducting qubits currently hold the most promise and investment, which positions them as a leading technology. While this approach may yield more qubits, it is susceptible to errors compared to ion trap qubits , which are recognized as a viable alternative. Unlike superconducting qubits that operate at extremely low temperatures—around 20 millikelvins or nearly -273 degrees Celsius—ion trap qubits leverage their unique properties while functioning in a less extreme environment.
Ion Traps: A Bright Future for Protein Folding
Ion trap technology currently serves as the primary alternative to superconducting qubits. Companies like IonQ and Honeywell are prominently advancing in this field, which operates on ionized atoms—atoms that possess a net charge, either positive or negative. This charge enables them to be isolated and confined within an electromagnetic field, comprising the foundation of ion trap technology.
IonQ effectively manipulates the quantum states of its ion trap qubits by cooling them to minimize computational noise, subsequently employing lasers to control these qubits. Notably, IonQ uses individual lasers for each ion, along with a global laser that can influence all ions simultaneously. Honeywell also leverages ionized atoms and lasers, although the process used to establish entanglement between two ions differs from the protocol employed by IonQ.
Understanding protein folding is crucial for finding solutions to Alzheimer’s and Parkinson’s disease.
Recently, a collaborative team from Honeywell and Kipu Quantum, a German startup specializing in quantum computing, achieved a remarkable milestone by employing a 36-qubit ion trap computer to tackle the complex issue of protein folding involving up to 12 amino acids. They developed a quantum optimization method aimed at identifying the optimal configurations of protein structures.
Though this endeavor seems daunting—and indeed it is—the crux of the matter lies in the ability of quantum computers, through the right algorithms, to assist scientists in comprehending the intricate mechanisms of protein folding that can lead to debilitating diseases like Alzheimer’s and Parkinson’s. Gaining a deeper understanding of this process is paramount for devising effective treatments.
This promising outcome signifies only the beginning. However, considerable work remains before quantum computers can reliably aid in combating these diseases. Firstly, the models surrounding protein folding must evolve to be more accurate and realistic. Furthermore, the classical algorithms responsible for refining the results generated by quantum algorithms need to be more precise. Despite these ongoing challenges, the achievements of these researchers serve as a profoundly promising springboard for future advancements in healthcare .
