The quantum computing industry is a rapidly evolving and expanding field with significant potential for growth and development in the coming years. According to Precedence Research, the size of the quantum computing industry is expected to grow by over 12 times from $10.13 billion in 2022 to $125 billion by the end of this decade. This would reflect a compound annual growth rate of 36.9% from 2022 to 2030. There has been a noteworthy increase in investment in the quantum computing industry in recent years, with governments, corporations, and venture capital firms all pouring funds into the development of quantum computing hardware, software, and applications.

As the demand for large-scale data analysis and simulation in the industry increases, quantum computing hardware and software development have become crucial. Notable startups in this sector, including Xanadu, ColdQuanta, and QC Ware, along with well-established corporations such as Alphabet Inc. (NASDAQ:GOOGL), Microsoft Corporation (NASDAQ:MSFT), Amazon.com, Inc. (NASDAQ:AMZN), International Business Machines Corporation (NYSE:IBM), D-Wave Systems (NYSE:QBTS), and IonQ, Inc. (NYSE:IONQ) are playing an important role in advancing quantum computing hardware and software. These companies have made significant strides in improving the stability, coherence, and number of qubits, which is a crucial step toward achieving large-scale quantum computing capabilities.

McKinsey has labelled quantum computing as one of the next big trends in the field of technology. Quantum computing, which is just one facet of the broader domain of quantum technology, holds significant promise and is projected to contribute approximately $1.3 trillion in value by the year 2035. In the coming years, the key players in the quantum computing industry are expected to progressively enhance the qubit capacity of their computers. However, this progress is anticipated to be gradual. According to McKinsey's estimation, by 2030, the number of operational quantum computers is expected to reach approximately 5,000 only. Furthermore, the development of hardware and software capable of handling the most intricate problems may not materialize until 2035 or even later. This projected timeline underscores the challenges involved in advancing quantum computing technology to its full potential.

Currently, prominent Wall Street banks are at the forefront of exploring the potential of quantum technology. A researcher from Goldman Sachs stated in January 2020 that quantum computing has the capacity to become a crucial technology. In addition to Goldman Sachs, other major players in the financial industry, such as JPMorgan and Citigroup, have also established their own quantum computing initiatives and have made investments in quantum computing startups. In 2020, JPMorgan conducted experiments using Honeywell International Inc.'s (NASDAQ:HON) quantum computer with the goal of streamlining mathematical operations that involve Fibonacci numbers. These initiatives show how financial organizations are becoming increasingly interested in using quantum computing to solve complex computational problems.

(NASDAQ:BIDU) has pioneered the development of a comprehensive quantum hardware-software integration solution, enabling access to a wide range of quantum chips through various platforms such as cloud services, mobile applications, and personal computers.

Here's what Horos Asset Management said about Baidu, Inc. (NASDAQ:BIDU) in its Q4 2022 investor letter:

As I mentioned at the beginning of this quarterly letter, we took advantage of the meltdown in technology platforms to initiate new positions in companies in which we had already been shareholders in the past and whose valuation did not, until now, provide a sufficiently high margin of safety. Such is the case of PayPal and Baidu, Inc.(NASDAQ:BIDU).

In the case of Baidu, as many will know, it is known as the Chinese Google. The company has been the leading Internet search engine in the Asian country for years, which has given it a historically privileged position to monetize, through online advertising, a huge user base. However, the rise of two types of applications has called into question the sustainability of its business model. On the one hand, mobile social apps, such as ByteDances well-known TikTok, have emerged as a new model of online consumption, generating a new platform through which to monetize Internet users. On the other hand, even more disruptive in the long term, is the emergence of the so-called super apps: a sort of virtual Swiss Army knives that allow users to access many products and services without having to leave their interface at any time, making Baidus traditional search engine less attractive. In this field, Tencent (with its super app Weixin/WeChat), Alibaba (Alipay) and Meituan certainly stand out. These two factors have caused Baidus online advertising market share to drop from 17% in 2017 to less than 7% estimated for 2022.34 To this deterioration, we should add the collapse in market value of its stake in iQiyi (video platform controlled by Baidu) and its equity holdings such as Trip.com (hotel and flight platform) (Click here to read the full text)

Market Capitalization: $115.29 billion

2022 Total Revenue: $60.53 billion

Diamond Hill Capital shared its outlook on International Business Machines Corporation (NYSE:IBM) in its Q4 2022 investor letter:

New positions initiated in Q4 included shortsInternational Business Machines Corporation (NYSE:IBM), Acushnet Holdings (GOLF) and elf Beauty (ELF). Since diversified information technology company IBMs 2019 acquisition of Red Hat, the company has aggressively pursued a hybrid cloud strategy. Though IBM and its new management team have made solid progress on this pivot, we believe the company still meaningfully lags the cloud hyperscalers and other cloud-native companies. Management has also laid out aggressive long-term targets for revenue growth and free cash flow, both of which we believe the company will struggle to achieve as it faces intense competition in its hybrid cloud business and structural headwinds in the companys legacy businesses.

Here's what ClearBridge Investments said about Intel Corporation (NASDAQ:INTC) in its Q3 2022 investor letter:

Also on the detractor side,Intel Corporation(NASDAQ:INTC) delivered a disappointing revenue miss and lowered full-year revenue and earnings guidance as COVID-19-driven demand for PCs abated (where Intel enjoys half its sales) and a delay in its flagship Sapphire Rapids CPU hurt its data center business. Despite these issues, we still believe Intel is an economically sensitive turnaround story with substantial upside.
